connections as it attempts to locate the correct node. A better design would use the longest possible prefix to represent all the interfaces on a node, and then a longer prefix on each interface that uniquely defines each interface.

At the end of this chapter, there are two worksheets (Table 3-4and Table 3-5) into which you can enter your WAN address values. If you are familiar with designing PNNI address structures, or if a plan is already completed, you can go directly to the Address Plan Worksheet and enter the values. The procedures for configuring ATM addresses on Cisco MGX and SES switch products are described in the following guides:

•Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Configuration Guide, Release 5

•Cisco SES PNNI Controller Software Configuration Guide, Release 3

Planning Address Configuration Settings

Use the following steps to create a WAN address plan:

Step 1 Select an ATM address format

Step 2 Select a PNNI level

Step 3 Select the PNNI peer group ID

Step 4 Select the ATM address

Step 5 Select the ILMI address prefix

Step 6 Select the SPVC address prefix

Step 7 Plan address prefixes for AINI and IISP links

Step 8 Select static addresses for UNI ports

These steps are described further in the remainder of this chapter.

Selecting an ATM Address Format

Each PNNI node must be configured for at least one ATM address format. This is an ATM requirement that must be considered when choosing PNNI addresses. To establish ATM connections, each ATM UNI end system must have at least one ATM End System Address (AESA) that uniquely identifies that ATM endpoint. This section explains the supported AESA address formats and their structures.

Caution Each node must support the address format of all its neighboring nodes.
