2. Configure routes:
# On Router A, configure static routes to 192.168.2.0/24 through the primary and backup
interfaces.
<RouterA> system-view
[RouterA] ip route-static 192.168.2.0 24 serial 2/1/0
[RouterA] ip route-static 192.168.2.0 24 serial 2/1/1
[RouterA] ip route-static 192.168.2.0 24 serial 2/1/2
# On Router B, configure static routes to 192.168.1.0/24.
<RouterB> system-view
[RouterB] ip route-static 192.168.1.0 24 serial 2/1/0
[RouterB] ip route-static 192.168.1.0 24 serial 2/1/1
[RouterB] ip route-static 192.168.1.0 24 serial 2/1/2
3. On Router A, configure backup interfaces and switchover delays:
# Specify Serial 2/1/1 and Serial 2/1/2 to back up Serial 2/1/0, and assign them a priority of
