Managing PNNI Nodes and PNNI Routing

This chapter provides procedures that you can use to manage Private Network-to-Network Interface

(PNNI) nodes and routes. This chapter includes the following sections:

• Managing PNNI Nodes

• Managing PNNI Route and Link Selection

• Displaying Node Configuration Information

Note The concepts behind the procedures in this chapter are introduced in the Cisco MGX and SES PNNI

Network Planning Guide.

Managing PNNI Nodes

The following sections describe how to configure upper level peer groups and how to manage the PNNI

node.

Creating Upper Level Peer Groups

Upper level peer groups enable routing from one PNNI peer group to another. If you are managing a

single peer group WAN, you do not need to create upper level peer groups.

Note The “Configuring PNNI Node Parameters” section in Chapter 2, “Configuring General Switch

Features,” describes how to configure the lowest level peer group parameter. Many upper level peer

group parameters are based on the lowest level peer group parameters. You should configure the basic

PNNI node parameters before creating upper level peer groups.

After you configure the lowest level PNNI nodes, all nodes within the same peer group can communicate

with each other. To enable communications between two nodes in a peer group, add a PNNI trunk

between them, as described in the “Cisco AXSM Software Configuration Guide and Command

Reference for the MGX 8850 (PXM45) and MGX 8950.” To enable routing between different peer

groups at the same level, you must create one or more upper level peer groups.
