VRRP-track-interface management collaboration configuration
example (the master monitors the uplink interface)
Network requirements
• As shown in Figure 20 , Client needs to access Host on the Internet. The default gateway of Client
is 10.1.1.10/24.
• AC 1 and AC 2 belong to VRRP group 1, whose virtual IP address is 10.1.1.10.
• When AC 1 works properly, packets from Client to Host are forwarded through AC 1. When VRRP
detects that there is a fault on the uplink interface of AC 1 through the interface management
module, packets from Client to Host are forwarded through AC 2.

Configuration procedure
1. Create VLANs, and assign corresponding ports to the VLANs, and configure the IP address of
each VLAN interface as shown in Figure 20 . (Details not shown.)
2. Configure a track entry on AC 1:
# Configure track entry 1, and associate it with the physical status of the uplink interface
VLAN-interface 3.
[AC1] track 1 interface vlan-interface 3
3. Configure VRRP on AC 1:
# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.
[AC1] interface vlan-interface 2
[AC1-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.10
# Set the priority of AC 1 in VRRP group 1 to 110.
[AC1-Vlan-interface2] vrrp vrid 1 priority 110
# Configure to monitor track entry 1 and specify the priority decrement as 30.
[AC1-Vlan-interface2] vrrp vrid 1 track 1 reduced 30
4. Configure VRRP on AC 2:
<AC2> system-view
[AC2] interface vlan-interface 2
# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.
