Configuration procedure
1. Configure the IP address of each interface as shown in Figure 19. (Details not shown.)
2. Configure Router 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.
<RouterA> system-view
[RouterA] 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.
[RouterA] 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.
[RouterA] 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.
[RouterA] nqa entry admin test
# Configure the test type as ICMP-echo.
[RouterA-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 Router A to Router B, and then to Router D through NQA.
[RouterA-nqa-admin-test-icmp-echo] destination ip 10.2.1.4
[RouterA-nqa-admin-test-icmp-echo] next-hop 10.1.1.2
# Configure the test frequency as 100 ms.
[RouterA-nqa-admin-test-icmp-echo] frequency 100
# Configure reaction entry 1, specifying that five consecutive probe failures trigger the Track
module.
[RouterA-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail
threshold-type consecutive 5 action-type trigger-only
[RouterA-nqa-admin-test-icmp-echo] quit
# Start the NQA test.
