Configuration procedure
1. Configure the IP address of each interface as shown in Figure 44 . (Details not shown.)
2. Configure LB 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.
system-view
[LBA] 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.
[LBA] 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.
[LBA] 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.
[LBA] nqa entry admin test
# Configure the test type as ICMP-echo.
[LBA-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 LB A to Router A, and then to LB B through NQA.
[LBA-nqa-admin-test-icmp-echo] destination ip 10.2.1.4
[LBA-nqa-admin-test-icmp-echo] next-hop 10.1.1.2
# Configure the test frequency as 100 milliseconds.
[LBA-nqa-admin-test-icmp-echo] frequency 100
# Configure reaction entry 1, specifying that five consecutive probe failures trigger the Track
module.
[LBA-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail threshold-type
consecutive 5 action-type trigger-only
[LBA-nqa-admin-test-icmp-echo] quit
# Start the NQA test.
[LBA] nqa schedule admin test start-time now lifetime forever
# Configure track entry 1, and associate it with reaction entry 1 of the NQA test group (with the
administrator admin, and the operation tag test).
[LBA] track 1 nqa entry admin test reaction 1
3. Configure Router A:
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.2.1.4.
system-view
[RouterA] ip route-static 30.1.1.0 24 10.2.1.4
# Configure a static route to 20.1.1.0/24, with the address of the next hop as 10.1.1.1.
[RouterA] ip route-static 20.1.1.0 24 10.1.1.1
4. Configure Router B:
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.4.1.4.
system-view
[RouterB] ip route-static 30.1.1.0 24 10.4.1.4
# Configure a static route to 20.1.1.0/24, with the address of the next hop as 10.3.1.1.
[RouterB] ip route-static 20.1.1.0 24 10.3.1.1
