Summary of Changes xxviii MRS V3.2 Protocol Config Ref V ol 2.
Chapter 1. APPN This chapter describes APPN and includes the following sections: v “What is APPN?” v “What APPN Functions Are Implemented on the Router?” on page 3 v “APPN Network Node Optio.
v A control point (CP), which manages the node’s resources v Resources owned by APPN end nodes and LEN end nodes that use the services of the network node APPN network nodes also: v Exchange information about the topology of the network.
LEN Nodes A LEN node is a T2.1 node without APPN extensions. A LEN node can establish peer connections with other LEN nodes, APPN end nodes, and APPN network nodes, as long as all of the required destination LUs are registered with the LEN node. A LEN node can also serve as a gateway between an APPN network and a SNA subarea network.

v X.25 SVC links v PPP links running over ISDN, V .25bis, or V .34 v Frame relay links running over ISDN v A TM SVC. 3. When the router activates a TG to an adjacent node, it negotiates with that node the maximum message size that can be sent across the TG.
APPN Network Node Optional Features In addition to the base APPN Architecture functions, the router also implements the following option set towers and new functions: 087 Garbage Collection Enhancemen.
Protocol (RTP) is used by the endpoints of the HPR connection. HPR intermediate nodes have no session or RTP connection awareness. This new transport layer features: v Selective retransmission error r.
parameter) must be used. The ISR traf fic uses LLC T ype 2 LAN frames. The HPR traff ic is handled in similar fashion to LLC T ype 1 LAN frames and must have a different SAP address. The default SAP address for HPR traf fic is X'C8'. If X'C8' has already been used by another protocol on a port, the default must be overridden.
v Layer 3 protocol ID = X'7085' SNA APPN/HPR (NLP) v Enterprise Extender Support for HPR over IP Refer to T able 2 on page 25 for a list of DLCs that support HPR. Note: HPR is not supported over SDLC, X.25, or DLSw ports. Dependent LU Requester (DLUR) The DLUR option extends the support of T2.
– Uninterrupted LU-LU sessions, if the supporting DLUS (SSCP) fails – SLU init, PLU init, and Third-party init Restrictions The DLUR option, as implemented on the router network node, has the following functional restrictions: v Only secondary LUs (SLUs) can be supported by the DLUR function.
* Below is SDLC ************************************************************************ *A20RT PATH PID=1, * DLURNAME=GREEN, * DLCADDR=(1,C,SDLCNS), * DLCADDR=(2,X,5353), 2 **port name * DLCADDR=(3,X.
*PU21LU2 LU LOCADDR=3 *PU21LU3 LU LOCADDR=4 ************************************************************************ Notes: 1 The difference between PU statement coding is: – For 2.0 definitions, the PU statement has IDBLK=...,IDNUM=.... – For 2.
Note: TGs for end nodes are not contained in the network topology database, but are contained in the node’s local topology database. TDUs do not flow through the network when a connection is established through a Connection Network or when an end node is made a member of a Connection Network.
A BrNN accomplishes: v Reduction of the number of network nodes in a large APPN network. v Hidden branch off ice topology from the WAN. v Direct, peer-to-peer communication between defined branches connected to the same connection network. v Reduces CP-CP session traf fic on the W AN link.
Network T opology Example Figure 1 shows many of the connectivity options provided by the BN function. In general, you can get from any network to any other network except that NetF can only reach network NetE and NetE is the only network that can reach NetF .
v Both ends of an inter-network link must be BNs, unless one of the networks is a peripheral network. In this case, the peripheral network may use a conventional non-BN network node to connect to the BN in the adjoining network. This is shown where peripheral network NetC connects to NetB with NNc.
With the branch extender in place the backbone network’s view of the branch extender is as a giant end node with all the downstream LUs being owned by this giant end node. The backbone has no knowledge of the topology downstream from the branch extender , thus reducing the overhead of topology exchanges.
focal point is designated by its entry points, which initiate communication with the focal point, the focal point is an implicit focal point . The focal point for the router can be either an explicit or implicit focal point. Routers configured as branch extender nodes have additional flexibility .
CP-MSU Control point management services unit. This message unit is generated by CPMS and contains alert information forwarded by the router entry point. CPMS passes CP-MSU message units to MDS. MDS-MU Multiple-domain support message unit. This message unit is generated by MDS.
The interval between attempts is doubled each time an attempt fails until a maximum interval of one day is reached. From that point on, the attempt is performed daily . Note: If an explicit focal point initiates a management session with a device, it will cause a session with an implicit focal point to terminate.
* PUJOE7 PU ADDR=12, IDBLK=077,IDNUM=EEEE7, 1 MAXPATH=8, ISTATUS=ACTIVE, MODETAB=LMT3270, USSTAB=STFTSNA2, ANS=CONT, MAXDATA=521, IRETRY=YES, MAXOUT=7, DLOGMOD=G22NNE, NETID=STFNET, PASSLIM=5, PUTYPE=.
A pool is a logical group of LUs. These LUs can be from dif ferent PUs or the same PU, different Host or same Host, etc. When a client specifies a specific pool name, any LU from the pool may be selected. There is always at least one implicit workstation pool.
A mixture of Pool and LU types(Workstation or Printer) can be added to a particular map. The resource selected will be based on the type of connection request. The order in which the resources are defined in the map will be the order in which it is chosen for a particular connection request.
in conjunction with the APPN DLUS/DLUR function. The APPN DLUS/DLUR solution allows the node to appear to VT AM as multiple PU devices, each supporting up to 253 dependent LUs. A node wishing to provide TN3270E Server services over a subarea connection for more than 253 clients simultaneously must also appear as multiple PUs to an attached host.
Enterprise Extender Support for HPR over IP Enterprise Extender support for HPR over IP allows HPR/APPN applications to run over an IP backbone network and still take advantage of APPN Class of Service. HPR over IP encapsulates HPR data into a UDP/IP packet for delivery over the IP network.
Configuration Changes That Require the APPN Function to Restart v Network ID of the network node v Control point name of the network node v XID number (of network node) for subarea connection v Adjac.
Minimum Configuration This group of APPN configuration steps: v Allows the network node to accept any request it receives from another node to establish a connection.
Notes: 1. APPN routing must be defined and enabled on the specific ports you configure the router network node to use. 2. Bridging and DLSw must still be enabled on the specific adapter ports you desire the device network node to use.
Note: Link stations do not have to be defined on every port, only those over which you want to initiate connections to adjacent nodes. 5. Enable the APPN network node. 6. Configure the following parameters for the APPN network node: v Network ID v Control point name 7.
v Enable DLSw on the node. v Define the DLSw ports with the following parameter: – Define a locally administered MAC address for DLSw – Disable the Service any node parameter 4.
have defined the adjacent link station to be a network node on one of the earlier configuration prompts. Answer no if you want the router to appear as a network node on this link.
After the temporary list is built, it is always ordered so that configured next-hop CPs are first followed by CPs associated with similarly named known resources. Additional reordering may be performed. Once all the reordering is complete, the extended border node starts searching for the target resource one CP after another .
Subnetwork visit count is the first of these, and describes the same concept as defined at the node level. When a port is first configured this parameter is initialized to the node setting. With this parameter you allow individual ports to deviate from the node level setting.
memory , and APPN shared memory . See “APPN Node T uning” on page 38 for a discussion of the APPN tuning parameters which control the amount of shared memory . Recall from the discussion under the set node prompt that configured routing lists are never modified by operational code.
The class of service mapping table allows for the conversion of non-native COS names to native COS names and vice versa. Non-native networks using the same COS names as the extended border node’s native network need not have a COS mapping table defined.
COS name. Each COS mapping table may have one of these default COS mapping entries. Y ou can never code a “*” as the native COS name. High-Performance Routing See T able 2 on page 25 for a list of ports that support HPR.
APPN on the router uses a set of default TG characteristics for each port (or DLSw port). These defaults, defined by the default TG characteristics parameter apply to all the TGs for link stations defined on a port unless they are overridden for a particular link station by the modify TG characteristics parameter .
are also three user-defined TG characteristics. Y ou may define these user-defined TG characteristics in order to bias the route selection calculation in favor of certain paths. Note: For DLSw ports the TG characteristics that you define ef fect only the selection of routes between APPN nodes over these DLSw ports.
v By manually setting the values of the maximum shared memory , percent of APPN shared memory to be used for buf fers , and the maximum cached directory entries tuning parameters using the talk 6 option of the command line interface.
v Module entry and exit traces specify component-level traces concerning the entry and exit of APPN modules. v General traces specify component-level traces concerning the APPN components. v Miscellaneous traces specify trace information about DLC transmissions and receptions.
T o enable collection implicitly , set create intermediate session records to yes. This setting will override the setting of collect intermediate session information . 2. Configuration changes to the APPN accounting parameters made using the talk 6 interface will not take effect until the router or the APPN function on the router is restarted.
7. If the attempt to reach the primary DLUS is unsuccessful, attempt to reach the backup DLUS. Example: – Assume the following parameter values: - Delay before initiating retries = 120 sec - Perform.
– If this retry fails, wait 60 seconds (the value of Short retry timer ). – Retry the primary DLUS. If this retry fails, retry the backup DLUS. This is attempt #1 of the Short retry count . – If this fails, wait 60 seconds (the value of Short retry timer ).
When configuring a DLSw port for APPN on the router , you assign the network node a unique MAC and SAP address pair that enables it to communicate with DLSw . The MAC address for the network node is locally administered and must not correspond to any physical MAC address in the DLSw network.
Virtual Routing Node (VRN). This TG identifies the direct connection from the port to the connection network. The CP name of the VRN is the connection network name.
Notes: 1. The same DLCI number must be specified on both ports. 2. The BDA address must be defined on the connection network definition. 3. The BNI addressees on both ports can be the same or different.
Notes: 1. The BDA address is not defined on the connection network definition. Example 5 Notes: 1. The same DLCI number must be specified on both ports. 2. The same BNI MAC address/SAP pair must be specified on both ports. 3. No BDA MAC address is specified on the connection network definition.
2. The DLCI number specified on the ports can be the same or different. 3. The BDA MAC address is not defined on the connection network definition. 4.

designated as seed routers. Seed routers are configured with the network range and zone list while all other routers are given null values. Null values indicate that the router should query the network for values from the seed routers.
The second identifier for the network is one or more ZoneNames. These ZoneName strings are not unique throughout the internet. The end station is uniquely identified by a combined object:type:ZoneName-string . A router first learns about a network when the new net range appears in the RTMP routing update from a neighboring router .
Other Commands: Y ou can use the AP2 CONFIG> list command to display all filter information for the interfaces. In addition, the list command accepts an interface# as an argument so that you can list information for only an interface. Sample Configuration Procedures This section covers the steps required to get AP2 up and running.
After you have specified the parameters, you can use the list command at the AP2 config> prompt to view your configuration. Setting Up Zone Filters Zone filtering lets you filter zones in each direction on each interface. T o filter incoming packets, set up an input filter .
This excludes Manufacturing zone information from entering Router A, thereby filtering the zone from the rest of the internet. Example 2 The following example shows how to filter the Manufacturing zone from Network 1 1-15, but still allow the Manufacturing zone to be visible on Network 1-5.
Following are some examples that explain how to set up network filters in the internet, as shown in Figure 13. The following steps show how to filter Network 6-10 so that it is not visible to Network 16-20 as shown in Figure 13. 1. Add an output network filter for Network 6-10 to Interface 2 on Router B.

v If the destination address does not equal the local VINES IP address or the broadcast address, VINES IP checks its routing tables for the next hop. If the hop count equals 0, VINES IP discards the packet. Otherwise, it decrements the hop count by one and forwards the packet to the next hop.
Service nodes maintain two tables: a routing table and a neighbor table. Both of these tables have timers that age their contents to eliminate out-of-date entries. Routing updates for X.25 interfaces occur when there is a change in the routing database, for example, when a node goes up/down or the metric changes.
Age (secs) The current age, in seconds, for the entry . If a router does not receive an update about a service node that is in the routing table at least every 360 seconds (6 minutes), the router removes the entry for that service node from the routing table.
updates, spaced 90 seconds apart, are sent to the services nodes that sent the routing response packets. Once the X.25 interface receives routing response packets from all of the X.25 destination nodes, routing requests are no longer sent to those X.25 addresses.
Each client node maintains a timer that has a default setting of two seconds. The timer starts when a client node transmits a query request or assignment request packet. The client node stops and resets the timer when it receives a query response packet.
T o communicate across X.25 WANs, VINES servers directly connected to the W AN need these two options: Server-to-server W AN X.25 support on the server (hardware and software). Running Banyan VINES over W AN Links When you set up a PPP , Frame Relay , or X.

Chapter 7. Using DNA IV This chapter describes IBM’s implementation of Digital Network Architecture Phase IV (DNA IV) and includes the following sections: v “DNA IV Overview” v “IBM’s Implem.
v DNA IV does not provide any Phase III compatibility features because it does not support the DDCMP data link protocols used by all Phase III nodes. v NCP (the router’s implementation of the DECnet Network Control Program) implements a subset of the original NCP commands and functions.
X.25 Data Link Addressing The router supports DECnet Phase IV over X.25 and can interoperate with routers running Digital’s implementation of DECnet Phase IV over X.25. Y ou set up the local and the remote DTE address with the set/define circuit command when you set up a DECnet circuit.
Area Routers If the router is configured as an area router , it maintains a similar database for all of the areas up to the maximum area, and can exchange area routing information with other area routers. Areas are handled almost exactly the same as nodes, except messages give costs to areas, but not nodes.
v Router NCP does not include the clear or purge commands, nor do the set commands have an all argument. The permanent database is always copied to the volatile database when the router starts, restarts, or boots. v A router NCP command can have only one argument.
Access control prevents the forwarding of DNA IV (Long Format) data packets on the basis of source address, destination address, and interface. Access control does not affect routing packets, because they use a dif ferent packet format. This makes configuring access control safer , because you cannot break the routing protocol.
nodes except node 1.9 because these two nodes share the same physical network. T o configure the desired access control for this example, build an inclusive filter on interface Eth/0 of router 1.19 as shown in the bottom of Figure 16 The first and second entries of the inclusive filter information shown in Figure 16 allow nodes 1.
Configure the desired access control for this example by building an exclusive filter on the PPP/0 interface of router 4.3 as shown in Figure 17. T o configure the example given for router 4.
Area routing filters allow you to configure a router to control the information about DECnet areas that are sent or accepted in level 2 routing messages. Y ou may configure separate incoming and outgoing filters for each interface. Each filter specifies which areas routing information will be passed to or accepted from.
Blending DECnet Domains DECnet has a 16-bit node address space with a fixed hierarchy of 6 bits of area and 10 bits of node. By comparison, IP has a 32-bit node address space with a flexible multilevel hierarchy . Many established networks have now grown to the point where they use all 63 areas.
Figure 19 on page 260 shows the areas that intersect are areas 1 and 2. The remainder of the areas can be duplicated between the two domains. In the example, there are two areas 3, 4, and 5, one in each domain. Note that it is never possible to allow direct connection between a node in area 3 in domain A and area 3 in domain B.
done by configuring routers 1.18 and 2.21 to only accept routes to areas 3, 4, 6, and 8 from domain A. Routers 2.17 and 2.21 would only accept routes for areas 5 and 9 from domain B.
There is still no way that a node in domain A area 5 can communicate directly to a node in domain B area 5. For nodes in these two areas to communicate, you must do a series of application-level relays using the set host command.

Chapter 9. Using OSI/DECnet V This chapter describes the router ’s implementation of the International Standards Organization’s (ISO) Open Systems Interconnection (OSI) Connectionless Network Layer .
Depending on the IS configuration, each IS can run three protocols: ES-IS, IS-IS, and Connectionless-Mode Network Protocol (CLNP). The ES-IS protocol enables the ESs and ISs attached to the same subnetwork to dynamically discover each other ’s existence.
The AFI specifies the type of IDI and the network addressing authority responsible for allocating the values of the IDI. The IDI specifies both the network addressing domain from which the values of the DSP are allocated and the network addressing authority responsible for allocating values of the DSP from that domain.

IS-IS Domain An IS-IS domain is a set of rules, administered by the same authority , that all ESs and ISs must follow to ensure compatibility . There are two types of domains that require discussion, administrative domain and routing domain.
Synonymous Areas When an L1 IS services more than one area, these additional areas are called synonymous areas. A router can support any number of synonymous areas, as long as there is an overlap of at least one area address between adjacent routers.
L1_A IS in area 2 must have area 1’s address added to its configuration and the L1 IS in area 1 must have area 2’s address added to its configuration.
v IS type (L1 only , or L1/L2) v Priority v LAN ID v If applicable, the system ID of the L1 designated IS (pseudonode) Upon receiving this message, the adjacent L1 IS extracts the source ID of the sending IS. This IS then constructs its own IIH message and places its source ID into the source ID field.
When more than one IS exists on a LAN, each IS compares the following to determine which IS will become the designated IS: v All ISs compare their priorities. The IS with the highest priority becomes the designated IS. v If the ISs have the same priority , they compare their source MAC addresses.
v Source ID v Set of area addresses that it services v IS type (L2) v System IDs and the cost of reaching IS adjacencies v If applicable, the system ID of the pseudonode v Address prefixes for ISs lo.
L2 Routing An L2 IS contains three routing tables: an L2 area-address routing table, an internal-metric reachable-address-prefix table (internal), and an external-metric reachable-address-prefix table (external). The following summarizes L2 routing: 1.
For example, a packet is destined to go from node A in domain 1 to node D in domain 2 ( Figure 26). Node A can choose two paths to send the packet, to node B and then on to D or to node C and then on to D. How nodes B and C advertise the cost of their routes to D determines how node A decides to route the packet, internally or externally .

Encoding an AFI An address prefix based entirely on the AFI is encoded only on the 1 octet AFI field.
listing of the transmit password is not in the receive password database, the packet is dropped. There are three types of transmit and receive passwords: domain, area, and circuit. A domain password provides security for L2 routing information. An area password provides security for L1 routing information.

includes the destination protocol address. The routers (that are also NHRP servers) along the routed path first check to see if the destination protocol address is an address that it can serve. If the router can satisfy the request, the router returns a Next Hop Resolution Reply with the NBMA address of the destination station.
information. So, for “one-hop” routing this operation happens once during transfer of a packet from its source to its destination. v The IBM implementation can operate in networks where some routers do not support NHRP .
NHRP in a Classic IP Environment with non-NHRP Device This example shows how NHRP can be used between two 1577 devices. when one of them does not support NHRP . Here, Device2 provides the NHRP client with the A TM address of the non-NHRP device and the client can establish a shortcut for traff ic to the non-NHRP host.
NHRP in a Pure LAN Emulation Environment In the LAN emulation case, routers use the IBM extensions to provide NBMA information for devices on their ELANs. When Device1 receives traff ic from host A destined to host B, it originates a Next Hop Resolution Request and sends it on the routed path.
This example also illustrates that the ELAN environment can be token-ring or Ethernet or any mixture of LAN types. NHRP in a Mixed Classical IP and ELAN Environment The NHRP function in the router can operate with both Classic IP and ELAN interfaces in the same network.
NHRP to an Egress Router The source and/or destination stations of protocol traff ic do not have to belong to subnets served by NHRP participants. They may access the A TM network via routers that communicate with the NHRP devices. In this case, the 2210 provides shortcuts through the A TM network to eliminate as many hops as possible.
NHRP Implementation NHRP interacts with the router function in the router . When the router function in the router is forwarding packets along the routed path and NHRP successfully obtains a shortcut VC, NHRP will update the router function to send the packet directly over the shortcut VC.
By default, the LSI will use the MAC address burned into the associated A TM adapter as the source MAC address of frames transmitted over the LANE shortcut VCCs.
NHRP Auto-Configuration NHRP is enabled by default if IP is present in the box. It can be disabled by entering the disable NHRP command from the NHRP config> prompt. See “Accessing the NHRP Configuration Process” on page 359 for additional information.
Extensions The NHRP protocol includes Extensions . Extensions are appended to NHRP packets. Extensions are used to request additional functions from the NHRP participants.
T o illustrate how to specify disallowed R2R shortcuts using protocol addresses and masks, consider the following network diagram: Example 1: An entry with address=9.9.9.1 mask=255.255.255.255 would cause the NHS to send a NAK to the sender of a Next Hop Resolution Request with destination protocol address 9.
Selecting the destination only option causes the router to deny shortcut requests from any NHRP client if any IP packets are being filtered to the destination address.
address, the selector , are assigned dynamically after the router is activated (and may change if the configuration of the router changes), unless you have configured a specific selector .
Chapter 12. Configuring and Monitoring NHRP This chapter describes how to configure and monitor the Next Hop Resolution Protocol (NHRP). For a description of this protocol, refer to “Next Hop Resolution Protocol (NHRP) Overview” on page 345.
Disable NHRP Use the disable command to disable NHRP on all interfaces not explicitly defined using an NHRP advanced config command.

Chapter 13. Using IP V ersion 6 (IPv6) This chapter describes how to use IPv6. IPv6 Overview IP V ersion 6 (IPv6) is a new version of the Internet Protocol. It is designed as a successor to IP V ersion 4 (IPv4). The following list identifies some of the advantages provided by IPv6: v Large address space IPv6 uses a 128-bit address.
Broadcast addressing has been replaced by multicast addressing in IPv6. IPv6 Address Format The IPv6 address is composed of 128 bits. These bits are written as eight 16-bit integers separated by colons. Example: ABCD:1234:0000:1234:5555:FFEE:7777:0123 Y ou can use the following simplifying rules: v Skip leading zeroes.
IPv6 Minimum MTU The minimum MTU for IPv6 is 1280 bytes. Y ou cannot enable IPv6 on an interface with an MTU less than 1280 bytes. IPv6 Mandatory Path MTU Discovery Path MTU Discovery is a protocol that allows a host to determine the maximum size packet that will successfully traverse a path to a destination without fragmentation.
4. Use the set acc on command at the IPv6 Config> prompt to enable access control. IPv6 Neighbor Discovery Protocol (NDP) IPv6 uses NDP to perform autoconfiguration.
Redirect If the source address of the packet and the next hop are on the same network, a router may send a redirect message informing the sender that the next hop is a neighbor . Use the p ndp command at the Config> prompt to configure NDP parameters.
the reverse path forwarding calculation on a received multicast datagram. Reverse path forwarding (rpf) is used to validate whether the received multicast datagram arrived on an interface that would be valid for forwarding to the source address contained in the multicast datagram.
