VRRP Configuration
Virtual Router Redundancy Protocol (VRRP) support on the G8124 provides redundancy 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. BLADE 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 Application Guide.

Command Syntax and Usage
vr <virtual router number (1-16)>
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 switches in
a hot-standby failover configuration where only one switch is active at any given time. To
view menu options, see page 301.
if <interface number>
Displays the VRRP Virtual Router Interface menu. To view menu options, see page 304.
track
Displays the VRRP Tracking menu. This menu is used for weighting the criteria used when
modifying priority levels in the master router election process. To view menu options, see
page 305.
