6.19 Configuring Router Redundancy
Router redundancy protocols use a virtual IP address to support a primary
router and multiple backup routers. The backup routers can be configured to
take over the workload if the master router fails, or can also be configured to
share the traffic load. The primary goal of router redundancy is to allow a host
device, which has been configured with a fixed gateway, to maintain network
connectivity in case the primary gateway goes down.
The ECN330-switch supports the Virtual Router Redundancy Protocol (VRRP).
VRRP requires the interface of one of the routers participating in the virtual
group to be specified as the address for the master virtual router. The protocol
then selects the backup routers based on the specified virtual router priority.
