Configuration procedure
1. Configure IP addresses for the interfaces. (Details not shown.)
2. Configure static routes and BFD:
# Configure static routes on Router A and enable BFD control packet mode for the static route
through Router D.
<RouterA> system-view
[RouterA] interface loopback 1
[RouterA-LoopBack1] bfd min-transmit-interval 500
[RouterA-LoopBack1] bfd min-receive-interval 500
[RouterA-LoopBack1] bfd detect-multiplier 9
[RouterA-LoopBack1] quit
[RouterA] ip route-static 120.1.1.0 24 2.2.2.9 bfd control-packet bfd-source 1.1.1.9
[RouterA] ip route-static 120.1.1.0 24 ethernet 1/2 10.1.1.100 preference 65
[RouterA] quit
# Configure static routes on Router B and enable BFD control packet mode for the static route
through Router D.
<RouterB> system-view
[RouterB] interface loopback 1
[RouterB-LoopBack1] bfd min-transmit-interval 500
[RouterB-LoopBack1] bfd min-receive-interval 500
[RouterB-LoopBack1] bfd detect-multiplier 9
[RouterB-LoopBack1] quit
[RouterB] ip route-static 121.1.1.0 24 1.1.1.9 bfd control-packet bfd-source 2.2.2.9
[RouterB] ip route-static 121.1.1.0 24 ethernet 1/2 13.1.1.2 preference 65
[RouterB] quit
# Configure static routes on Router C.
<RouterC> system-view
[RouterC] ip route-static 120.1.1.0 24 ethernet 1/2 13.1.1.1
