230 CHAPTER 16: CONFIGURING LAPB AND X.25
SVC Application of XOT I. Networking Requirement
Router B and C connect through Ethernet interface, and build TCP connection
between them. X.25 packets forward through TCP, and configure SVC to
implement the SVC function.

III. Configuration Procedure
1Configure Router A
aBasic 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
