Virtual Router ID (VRID)

The VRID must be configured with the same value on each virtual router associated with the
redundant IP address (IP addresses). It is placed in all VRRP advertisement messages sent by each
virtual router.

Priority

The priority value affects the interaction between this VRID and the same VRID of other virtual
routers participating on the same LAN. A higher priority value defines a greater priority in
becoming the virtual router master for the VRID. The priority value can only be configured when
the defined IP address on the IP interface is different than the virtual router IP address (non-owner
mode).
