VRRP Configuration
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.

Command Syntax and Usage
vr <virtual router number (1-1024)>
Displays the VRRP Virtual Router Menu. This menu is used for configuring virtual routers on this
switch. To view menu options, see page 296.
group
Displays the VRRP virtual router group menu, used to combine all virtual routers together as one
logical entity. 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.
track
Displays the VRRP Tracking Menu. This menu is used for weighting the criteria used when modi-
fying priority levels in the master router election process. To view menu options, see page 303.
