Network requirements
z
As shown in
, Host A needs to access Host B on the Internet. The default gateway of
Host A is 10.1.1.10/24.
z
Switch A and Switch B belong to VRRP group 1, whose virtual IP address is 10.1.1.10.
z
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 corresponding ports to the VLANs, and configure the IP address of
each VLAN interface as shown in
. 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
