Chapter 5

Conﬁguring Router Redundancy

This chapter describes how to conﬁgure router redundancy. It assumes you have

read Conﬁguring Routers and Chapter 2 and Chapter 3 of this guide, and that you

have already created a local conﬁguration ﬁle for a router without router

redundancy.

To enable router redundancy, you must choose at least two routers as members of

a router redundancy group. One of the routers will be the primary router; it will

provide normal routing/bridging services. The other router will be the secondary,

backup router; it will take over if the primary router fails. All members of a router

redundancy group must have exactly the same conﬁguration for all backed-up

interfaces, except for the router’s Member ID, Priority, and resources.

When you enable router redundancy, you must conﬁgure some group and member

parameters. The Conﬁguration Manager supplies default values for the remaining

parameters. Use the directions that follow to enable router redundancy and edit

router redundancy parameters.

For each parameter, this chapter provides information about default settings, valid

parameter options, the parameter function, instructions for setting the parameter,

and the MIB object ID.

Note: You cannot conﬁgure router redundancy in dynamic or remote mode.
