VRRP-Track-interface management collaboration configuration
example
In this example, the master monitors the uplink interface.
Network requirements
As shown in Figure 26 , Host A needs to access Host B on the Internet. The default gateway of Host A is
10.1.1.10/24.
Switch A and Switch B belong to VRRP group 1, whose virtual IP address is 10.1.1.10.
When Switch A works correctly, packets from Host A to Host B are forwarded through Switch A. When
VRRP detects that a fault is on the uplink interface of Switch A through the interface management module,
packets from Host A to Host B are forwarded through Switch B.

Configuration procedure
1. Create VLANs and assign corresponding ports to them. Configure the IP address of each VLAN
interface as shown in
Figure 26 . (Details not shown.)
2. Configure a track entry on Switch A:
# Configure track entry 1 and associate it with the link status of the uplink interface VLAN-interface
3.
[SwitchA] track 1 interface vlan-interface 3
3. Configure VRRP on Switch A:
# Create VRRP group 1 and configure the virtual IP address 10.1.1.10 for the group.
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.10
# Set the priority of Switch A in VRRP group 1 to 110.
[SwitchA-Vlan-interface2] vrrp vrid 1 priority 110
# Configure to monitor track entry 1, and specify the priority decrement as 30.
[SwitchA-Vlan-interface2] vrrp vrid 1 track 1 reduced 30
4. Configure VRRP on Switch B:
