Configure the standby interfaces and switch delays on Router A:
# Specify interfaces Serial 2/1 and Serial 2/2 on Router A to back up Serial 2/0, and assign
them the priorities 30 and 20, respectively.
[RouterA] interface serial 2/0
[RouterA-Serial2/0] standby interface serial 2/1 30
[RouterA-Serial2/0] standby interface serial 2/2 20
# Configure switchover delays to 10 seconds.

Verify the configuration on Router A:
# Display the state of the active and standby interfaces.
