22 Configuring VRRP
The Virtual Router Redundancy Protocol (VRRPv2/VRRPv3) is a standard router redundancy protocol
supported in IPv4/IPv6, based on RFC 3768 and RFC 2787. It provides redundancy by eliminating the
single point of failure inherent in a default route environment
.
The VRRPv2/VRRPv3 router, which
controls the IPv4/IPv6 address associated with a virtual router
is called the master router, and is responsi-
ble for forwarding virtual router advertisements. If the master router becomes unavailable, the highest
priority backup router will transition to the master state. The Alcatel-Lucent implementation of VRRP also
supports the collective management of virtual routers on a switch.
Note
. This VRRPv3 implementation is based on the latest Internet Draft, Virtual Router Redundancy
Protocol for IPv6, September 2004.
Note
. RFC 3768, which obsoletes RFC 2338, does not include support for authentication types. As a
result, configuring VRRP authentication is no longer supported in this release.
In This Chapter
This chapter describes VRRPv2/VRRPv3 and how to configure it through the Command Line Interface
(CLI). CLI commands are used in the configuration examples; for more details about the syntax of
commands, see the
OmniSwitch CLI Reference Guide
.
