Chapter 23 Configuring Vrrp; In This Chapter - Alcatel-Lucent OmniSwitch 9900 Series Network Configuration Manual

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
controls the IPv4/IPv6 address associated with a virtual router is called the master router, and is
responsible for forwarding virtual router advertisements. If the master router becomes unavailable, the
highest priority backup router will transition to the master state. The OmniSwitch implementation of
VRRP also supports the collective management of virtual routers on a switch.
Notes.
•
Throughout the rest of this chapter, the feature name, "VRRP", refers to both VRRPv2 and VRRPv3.
However, "VRRPv2" and "VRRPv3" are used explicitly to highlight any differences.
•
This VRRPv3 implementation is based on the Internet Draft, Virtual Router Redundancy Protocol for
IPv6, September 2004.
•
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 VRRP 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 AOS Release 8 CLI Reference Guide.
