When the active router in a VRRP (Virtual Router Redundancy Protocol) group fails, the router with the highest priority in the group takes over as the new active router and begins forwarding packets. This router is known as the standby router.
The VRRP protocol provides redundancy for IP networks, allowing multiple routers to participate in a virtual router group that shares a virtual IP address. One router assumes the active role and forwards packets sent to the virtual IP address, while the other routers in the group assume a standby role and monitor the active router's status.
If the active router fails, the standby router with the highest priority takes over the active role and begins forwarding packets. The priority is assigned by the network administrator and determines which router will assume the active role if multiple standby routers are available.
The backup router is not a defined term in VRRP, but it could refer to any router in the group that is not currently the active router or the standby router.
The listening state is also not a defined term in VRRP. However, when a router first joins a VRRP group, it starts in the initialization state, where it sends out VRRP advertisements but does not forward packets. It then moves to the backup state, where it monitors the active router's status and can assume the active role if needed.
In summary, when the active router in a VRRP group fails, the standby router with the highest priority assumes the active role and begins forwarding packets. The backup and listening states are not defined terms in VRRP, but refer to routers in the group that are not currently the active or standby router or routers that are in the initialization or backup state, respectively.
