Planning Address Configuration Settings; Selecting An Atm Address Format - Cisco Network Router User Manual

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
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:

Planning Address Configuration Settings

Use the following steps to create a WAN address plan:
Select an ATM address format
Step 1
Select a PNNI level
Step 2
Select the PNNI peer group ID
Step 3
Step 4 Select the ATM address
Select the ILMI address prefix
Step 5
Select the SPVC address prefix
Step 6
Step 7 Plan address prefixes for AINI and IISP links
Select static addresses for UNI ports
Step 8
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.
Each node must support the address format of all its neighboring nodes.
