Observe failover and tracking

The client uses a shared virtual gateway, and both routers have separate uplinks.

Configure the same HSRP group and virtual address on the shared network.

Track the preferred uplink and lower the router priority if that link goes down.

The preferred router starts active, and the backup router is on standby.

Check the hello and hold timers, then test reachability through the virtual gateway.

Shutting down the backup uplink leaves the preferred router active.

Restore the backup uplink before shutting down the tracked uplink.

The tracking object goes down and lowers the preferred router priority.

The backup router takes over while the client keeps the same virtual gateway.

Ping the upstream loopback again to verify forwarding after failover.

Restore the tracked uplink and confirm that its priority returns.

The preferred router becomes active again, and the client can still reach the loopback.
