III. Configuration Procedure

1Configure Router A

a Basic X.25 Configuration

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

[Router-Serial0]x25 x121-address 1

[Router-Serial0]x25 map ip 1.1.1.2 x121-address 2

[Router-Serial0]ip address 1.1.1.1 255.0.0.0

2Configure Router D

aBasic X.25 Configuration

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

[Router-Serial0]x25 x121-address 2

[Router-Serial0]x25 map ip 1.1.1.1 x121-address 1

[Router-Serial0]ip address 1.1.1.2 255.0.0.0

3Configure Router B

aStart X.25 switching

[Router]x25 switching

bConfigure X.25 local switching

[Router]x25 switch svc 1 interface serial 11/0/2

cConfigure XOT switching

[Router]x25 switch svc 2 xot 10.1.1.2

dConfigure ethernet 0.

[Router]interface ethernet 0 [Router-Ethernet0]ip address 10.1.1.1 255.0.0.0

eConfigure Serial 11/0/2

[Router-Ethernet0]interface serial 0 [Router-Serial0]link-protocol x25 dce ietf
