VRRP utilizes a virtual router identifier, or VRID, to exchange VRRP protocol messages over multicast with other routers using the same VRID to determine which is the master router. The VRID is 8 bits in length and the valid range is 1-255. Because each project uses a single administrative network for VRRP communication between routers, individual projects are limited to 255 highly-available routers.
