interface router and is, therefore, the IP address owner. It also becomes the virtual router mas-
ter. Web switch 2 is a virtual router backup. Its real interface is configured with an IP address
that is on the same subnet as the virtual interface router but is not the IP address of the virtual
interface router.
The virtual interface router has been assigned a VRID = 1. Therefore, both of the VRRP rout-
ers have a MAC address = 00-00-5E-00-01-01.
