[Router-Serial0]interface serial 0.1
aCreate sub-interface serial 0.1
[Router-Serial0.1]ip address 10.1.1.2 255.255.0.0
[Router-Serial0.1]x25 map ip 10.1.1.1 x121-address 200
bCreate sub-interface serial 0.2
[Router-Serial0.1]interface serial 0.2
[Router-Serial0.2]ip address 20.1.1.2 255.255.0.0
[Router-Serial0.2]x25 map ip 20.1.1.1 x121-address 300
2Configure Router B:
