Virtual Router Redundancy Protocol
If you configure a static route between a device and router (or switch) that is processing
the device’s routed traffic, you are effectively introducing a potential single point of
failure into the network. If the router goes down, the device is unable to communicate.
Virtual Router Redundancy Protocol (VRRP) can provide a backup mechanism through
the use of a primary and secondary router.
If the primary router goes down, VRRP can let the secondary router take over from the
primary router without affecting the device that uses the static route. The device uses
a virtual IP address that is recognized by the secondary router if the primary router goes
down.
You can configure physical ports or routed VLANs as VRRP router ports. The ports that
participate in VRRP use an election protocol that determines which port functions as
the primary router. You can configure multiple ports on the switch as virtual router ports.
A single port can be visible to the network as more than one virtual router.
