Configuration Examples

This chapter describes how to configure a ServerIron ADX to configure the following router redundancy protocols:

•	Virtual Router Redundancy Protocol (VRRP) – The standard router redundancy protocol described in RFC 2338.

•	VRRP Extended (VRRP-E) – An enhanced version of VRRP that overcomes limitations in the standard protocol.

NOTE: You can use a Brocade Layer 3 Switch configured for VRRP with another Brocade Layer 3 Switch or a third-party router that is also configured for VRRP. However, you can use a Brocade Layer 3 Switch configured for VRRP-E only with another Brocade Layer 3 Switch that also is configured for VRRP-E.
