VRRP-track-interface management collaboration configuration
example (the master monitors the uplink interface)
Network requirements
•
As shown in Figure 59 , 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 normally, packets from Host A to Host B are forwarded through Switch A.
When VRRP detects that there is a fault 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 ports to the VLANs, and configure the IP address of each VLAN
interface as shown in Figure 59 . The configuration procedure is omitted.
2.
Configure a track entry on Switch A.
# Configure track entry 1, and associate it with the physical 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
