# The output on Router B is similar to that on Router A. When the master route fails, the hosts in
30.1.1.0/24 can still communicate with the hosts in 20.1.1.0/24.

VRRP-track-interface management collaboration configuration
example
In this example, the master monitors the uplink interface.
Network requirements
As shown in Figure 61, Host A needs to access Host B on the Internet. The default gateway of Host A is
10 .1.1.10 / 2 4 .
Router A and Router B belong to VRRP group 1, whose virtual IP address is 10.1.1.10.
When Router A works correctly, packets from Host A to Host B are forwarded through Router A. When
VRRP detects that a fault is on the uplink interface of Router A through the interface management module,
packets from Host A to Host B are forwarded through Router B.
