Configuration Guide for Cisco DSLAMs with NI-2

Chapter 3 Initially Configuring the Cisco DSLAM

Configuring the Network Routing

For network routing, the default software image for the DSLAM contains the PNNI routing protocol.

The PNNI protocol provides the route dissemination mechanism for complete plug-and-play capability.

This section describes modifications you can make to the default PNNI or Interim-Interswitch Signaling

Protocol (IISP) routing configurations.

Use the atm route command to configure a static route. Static route configuration allows ATM call setup

requests to be forwarded on a specific interface if the addresses match a configured address prefix.

Note An interface must be UNI or IISP if it is configured with a static route. Static routes configured as PNNI

interfaces default as down.

Example

This example shows how to use the atm route command to configure the 13-byte peer group prefix as

47.0091.8100.567.0000.0ca7.ce01 at ATM 0/1:

DSLAM(config)# atm route 47.0091.8100.567.0000.0ca7.ce01 atm 0/1

DSLAM(config)#

NI-2 Card Redundancy Overview

The NI-2 Card redundancy feature provides redundancy on the Cisco 6130, Cisco 6160, and Cisco 6260

DSLAM systems. This redundancy feature has two main components.

• Recovery from failure on an NI-2 card lets the standby card take over if the active card fails.

• Recovery from failure due to a cut fiber or the failure of an optical transmitter or receiver

(SONET APS) lets the active NI-2 switch to the fiber interface on the standby NI-2.

NI-2 Cold Redundancy

On a system with two NI-2 cards of the same interface types (trunk and subtend), the NI-2 cold

redundancy feature allows a standby NI-2 card to assume system operations if the active NI-2 card

completely fails. The NI-2 card in slot 10 is called the primary card and the card in slot 11 is called the

secondary card. Either card can be active or standby.
