This status can be checked by using the command show ip vrrpextended.INTERNETe4e4e110.1.1.11/24VRID: 10.1.1.1 (Master)e110.1.1.12/24VRID: 10.1.1.1 (backup)Host A10.1.1.10/24default gateway: 10.1.1.1Now, we've assigned Host A with a default gateway of 10.1.1.1, and it will letthe routers do the work, as to who handles the traffic. Router A has the higherpriority, so it is currently master of the VRID. Router B is standing by, ready totake over should Router A fail or its priority drop below 150.Brocade IP Primer 315
