VRRP Configuration
Virtual Router Redundancy Protocol (VRRP) support on the switch 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 BLADE OS 5.1 Application Guide.
