Track Configuration Examples
VRRP-Track-NQA Collaboration Configuration Example (The Master Monitors the
Uplink)
Network requirements
z As shown in Figure 12-2 , 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 finds that there is a fault on the uplink of Switch A through NQA, 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 Figure 12-2. The configuration procedure is omitted.
2) Configure an NQA test group on Switch A.
