Implementation Notes

This chapter provides information about special features of Bay Networks

interface and router redundancy.

Planning Your Network

Conﬁguring router redundancy on your network is somewhat different from

conﬁguring most protocols, because router redundancy involves multiple nodes.

Consider your network requirements and design your interface and router

redundancy groups carefully to maximize the beneﬁts of using redundancy. In

particular, keep in mind the following characteristics of router and interface

redundancy:

• The interfaces you conﬁgure as backed-up interfaces should perform routing

services that you rate as your highest priority.

• Remember that if a router becomes the primary router in a router redundancy

group, other functions it has been performing while in the secondary role

terminate.

• Bay Networks recommends that you conﬁgure redundant routers as dedicated

redundant routers, that is, with the backup role as their sole function.

• A router can be a member of only one router redundancy group.

When planning your network for router redundancy, follow these guidelines:

1. Determine the backed-up interfaces in each member of the router redundancy

group.

2. Select the group ID and member IDs for router redundancy, noting the

following:

a. The group ID must be unique for each group in the network.
