• Configure static routing-Track-NQA collaboration to determine whether the master route is
available in real time. If the master route is unavailable, the backup route takes effect, and Switch
D forwards packets to 20.1.1.0/24 through Switch C.

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 54 . (Details not shown.)
2. Configure Switch A.
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.1.1.2 and the
default priority 60. This static route is associated with track entry 1.
<SwitchA> system-view
[SwitchA] ip route-static 30.1.1.0 24 10.1.1.2 track 1
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.3.1.3 and the
priority 80.
[SwitchA] ip route-static 30.1.1.0 24 10.3.1.3 preference 80
# Configure a static route to 10.2.1.4, with the address of the next hop as 10.1.1.2.
[SwitchA] ip route-static 10.2.1.4 24 10.1.1.2
# Create an NQA test group with the administrator admin and the operation tag test.
[SwitchA] nqa entry admin test
# Configure the test type as ICMP-echo.
[SwitchA-nqa-admin-test] type icmp-echo
# Configure the destination address of the test as 10.2.1.4 and the next hop address as 10.1.1.2
to check the connectivity of the path from Switch A to Switch B, and then to Switch D through NQA.
[SwitchA-nqa-admin-test-icmp-echo] destination ip 10.2.1.4
[SwitchA-nqa-admin-test-icmp-echo] next-hop 10.1.1.2
# Configure the test frequency as 100 milliseconds.
[SwitchA-nqa-admin-test-icmp-echo] frequency 100
# Configure reaction entry 1, specifying that five consecutive probe failures trigger the Track
module.
