Chapter 12

Configuring VRRP and VRRPE

This chapter describes how to configure HP routing switches 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 an HP routing switch configured for VRRP with another HP routing switch or a third-party router that is also configured for VRRP. You can use an HP routing switch configured for VRRPE only with another HP routing switch that also is configured for VRRPE.

Standby Router Protocol (SRP), an HP router redundancy protocol available before VRRP or VRRPE, is described in “Configuring SRP” on page 13-1.

For a summary of how these three router redundancy protocols differ, see “Comparison of VRRP, VRRPE, and SRP” on page 12-8.
