Virtual Router Redundancy Protocol (VRRP) support on GbE Switch Modules provides redun- dancy between routers in a LAN. This is accomplished by configuring the same virtual router IP address and ID number on each participating VRRP-capable routing device. One of the virtual routers is then elected as the master, based on a number of priority criteria, and assumes control of the shared virtual router IP address. If the master fails, one of the backup virtual routers will assume routing authority and take control of the virtual router IP address.

By default, VRRP is disabled. Alteon OS has extended VRRP to include virtual servers as well, allowing for full active/active redundancy between switches. For more information on VRRP, see the “High Availability” chapter in the Alteon OS 21.0 Application Guide.

Group options must be configured when using two or more Alteon switches in a hot- standby failover configuration where only one switch is active at any given time. To view menu options, see page 299.

if <interface number (1-127)>

Displays the VRRP Virtual Router Interface Menu. To view menu options, see page 302.
