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 select 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.

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

global 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 Management Information Base (MIB) object ID.

Enabling Router Redundancy

To conﬁgure a router redundancy group, you create a group conﬁguration ﬁle. You

then use this ﬁle as a template and apply it to each member of the group twice:

once as a primary ﬁle, which the router uses when it boots as the primary member

of the redundancy group, and then as a secondary ﬁle, which the router uses in its

role as secondary member.

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