Configuring PNNI Routing
This chapter describes how to configure the ATM Private Network-to-Network
Interface (PNNI) routing protocol and routing hierarchies in your Lucent network.
The PNNI is a standard designed by the ATM Forum. This standard defines both an
ATM routing protocol and an ATM signaling protocol. Lucent supports PNNI on the
CBX 3500, CBX 500, and GX 550 Multiservice switch platforms.
For a detailed explanation of PNNI routing and signaling, see the ATM Forum
Technical Committee Private Network-Network Interface Specification Version 1.0
(af-pnni-0055.000), available from the ATM Forum’s Web site:
http://www.atmforum.com.
