5.8.4 VRRP

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic
assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and
reliability of routing paths via automatic default gateway selections on an IP sub-network.

ID of the route. This ID is different for each virtual router on the network
Master routers have a priority of 255 and backup router(s) can have priority
between 1 and 254.
The virtual IP address that both virtual routers share.
A virtual router must use 00-00-5E-00-01-XX as its (MAC) address. The last byte of
the address (XX) is the Virtual Router Identifier (VRID), which is different for each
virtual router in the network. This address is used by only one physical router at a
time, and is the only way that other physical routers can identify the master
router within a virtual router.
