Chapter 21

Configuring VRRP and VRRPE

This chapter describes how to configure Foundry routers to configure the following router redundancy protocols:

• Virtual Router Redundancy Protocol (VRRP) – The standard router redundancy protocol described in RFC

2338.

• VRRP Extended (VRRPE) – An enhanced version of VRRP that overcomes limitations in the standard

protocol.

NOTE: VRRP and VRRPE are separate protocols. You cannot use them together.

NOTE: You can use a Foundry Layer 3 Switch configured for VRRP with another Foundry Layer 3 Switch or a

third-party router that is also configured for VRRP. You can use a Foundry Layer 3 Switch configured for VRRPE

only with another Foundry Layer 3 Switch that also is configured for VRRPE.

Foundry Standby Router Protocol (FSRP), a Foundry router redundancy protocol available before VRRP or

VRRPE, is described in “Configuring FSRP” on page 22-1.

For a summary of how these three router redundancy protocols differ, see “Comparison of VRRP, VRRPE, and

FSRP” on page 21-8.
