| Configuring the WSM using Device Manager |

VRRP eliminates single points of failure within a network by enabling redundant router LAN configurations that provide alternate router paths for a host. Each participating VRRP-capable routing device is configured with the same virtual router IP address and ID number.
One of the virtual routers is 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 take control of the virtual router IP address and actively process traffic addressed to it. Because the router associated with a given alternate path supported by VRRP uses the same IP address and MAC address as the routers for other paths, the host's gateway information does not change, no matter what path is used.
VRRP-based redundancy reduces administrative overhead because hosts need not be configured with multiple default gateways.
By default, VRRP is disabled. For VRRP configuration examples, see the High Availability chapter in the Web OS Switch Software 10.0 Application Guide, part number 212777-A.
