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.
