VRRP Commands

Introduction

This chapter contains the Virtual Router Redundancy Protocol (VRRP) commands.

for the BSR 64000™.

VRRP specifies an election protocol that dynamically assigns responsibility for a

virtual router to one of the VRRP routers on a LAN. The VRRP router controlling the

IP address or addresses associated with a virtual router is called the Master, and

forwards packets sent to these IP addresses. The election process provides dynamic

failover in the forwarding responsibility if the Master becomes unavailable. This

allows any of the virtual router IP addresses on the LAN to be used as the default

first-hop router by end-hosts. VRRP provides a higher-availability default path

without requiring configuration of dynamic routing or router discovery protocols on

every end host.
