III.Configuration Procedure

1 Configure Router A:

[Router]interface serial 0 [Router-Serial0]link-protocol x25 dte

[Router-Serial0]x25 x121-address 100

[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:

[Router]interface serial 0 [Router-Serial0]link-protocol x25 dte

[Router-Serial0]x25 x121-address 200

[Router-Serial0]x25 map ip 10.1.1.2 x121-address 100

3Configure Router C:

[Router]interface serial 0 [Router-Serial0]link-protocol x25 dte

[Router-Serial0]x25 x121-address 300

[Router-Serial0]x25 map ip 20.1.1.2 x121-address 100

4Configure Router D:

[Router]interface serial 0 [Router-Serial0]link-protocol x25 dce

[Router-Serial0]interface serial 1

[Router-Serial1]link-protocol x25 dce

[Router-Serial1]interface serial 2

[Router-Serial2]link-protocol x25 dce

[Router-Serial2]quit[Router]x25 switching

[Router]x25 switch svc 100 interface serial 0

[Router]x25 switch svc 200 interface serial 1

[Router]x25 switch svc 300 interface serial 2
