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 Optional Features” on page 6 v “Supported DLCs” on page 25 v “Router Configuration Process” on page 25 v “APPN Configuration Notes” on page[...]

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. This information is exchanged each time network nodes establish a connection or when there is a change in the [...]

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. Because a LEN [...]

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. If a BIND message is larger than the negotiated message size, the router segments the BIND. [...]

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 Enhancements 1002 Adjacent Link Station name 1007 Parallel TGs 1012 LU name = CP name 1016 Extended Border Node 1061 Prerequisites for SS Extensions for NNS Sup[...]

Note: HPR is not supported over SDLC, X.25, or DLSw ports. Dependent LU Requester (DLUR) The DLUR option extends the support of T2.0 or T2.1 devices containing dependent LUs to [...]

– 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. An LU supported by DLUR cannot function as a primary[...]

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. Because the connectivity is represented by a TG from [...]

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. The following are limitations of Branch Extender: v Networ[...]

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 . Note: Solid lines represent intersubnetwork TGs. In this figure: v Netid subnetwork NetA[...]

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. v Any LU in networks NetA, NetB, NetC, NetD, or Ne[...]

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. Conversely , the branch extender’s netwo[...]

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 . As with conventional network nodes, the focal poi[...]

MDS-MU Multiple-domain support message unit. This message unit is generated by MDS. It encapsulates the CP-MSU for transport between nodes. SNMP Capabiliti[...]

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. Dynamic Definition of Dependent LU[...]

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. This pool is referred to as the global default pool. The name of this Pool is defined [...]

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. How LUs are Chosen For Client Connections When IP Addres[...]

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. Su[...]

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. Supported DLCs T able 2 shows the DLC ports supported by t[...]

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 Adjacent node type (of link station) v Change of node function (EBN, BN, NN) v Any parameters under the following options: – High-Performance Routing (HP[...]

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. v Restricts the network node from initiating connections with other nodes. If you choose the minimum configuration steps, adjacent nodes must define connections to the router netw[...]

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.

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 . Note that once the [...]

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. Adjacent subnetwork af filiation is controlled by the other new exten[...]

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. When the extended border node uses a given routing list it co[...]

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. If only some of the non-native COS names differ from the native COS names, then only those th[...]

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. See “Configuration Requirements for APPN” on page 26 for information about configuring the protocols that support APPN [...]

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 . These default TG characteristic[...]

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. These characteristics have no[...]

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. APPN T race Enhancements The following are enhancements to the APPN trac[...]

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 short retries to restore disrupted pipe = yes - Short retry timer =6 0s e c - Short retry count =2 - Perform long retries to restore disrupted pipe =[...]

This is attempt #1 of the Short retry count . – If this fails, wait 60 seconds (the value of Short retry timer ). – Retry the primary DLUS, and then the backup DLUS. This is attempt #2 Short retry c[...]

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. APPN Frame Relay BAN Connection Network Implementation T[...]

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. Since the connectivity is represented by a TG from a given node to a VRN, normal topology and routing services (TRS) can be used by the network node server to calculate the direct path[...]

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. 4. If the APPN node initiates the connection to the device, the APPN port that gets chosen for the connection is dependent upon which port respo[...]

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. 4. If the APPN node initiates the connection to [...]

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.

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. When a network sends a[...]

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. The problem is that as dif ferent facilities connec[...]

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. The best that you ca[...]

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. Therefore, nodes in the intersection see a universe that contains areas 1 and 2 from the intersection, areas 3, 4, 6, and 8 from domain A, and areas 5 and 9 from doma[...]

There is still no way that a node in domain A area 5 can communicate directly to a node in domain B area 5.

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. An ES connected to the same subnetwork as an IS is adjacent to the IS.

Synonymous Areas When an L1 IS services more than one area, these additional areas are called synonymous areas.

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. An L2 IS receives a packet and compares the destination address in the header of the packet to [...]

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 . There ar[...]

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. It is possible, though unlikely , that this could confuse some end-station protocol stack implementations, since the MAC address will not match that of the router that the end-station uses[...]

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. When using an existing configuration file, NHRP is enabled by default if it was not pr[...]

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 9.9.9.1 (HOST1). Since 9.9.9.1 is not dire[...]

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. If NHRP clients should not be trusted, destination only should be selected. destination only might be the best option when NHRP clients are non-routers with multiple IP addresses or[...]

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. v Routing Using[...]

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. Example: ABCD:1234:0:1234:0:F[...]
