SVC application of XOT

As shown in Figure 142, set up a TCP connection between Router B and Router C to deliver data between Serial 2/0 of Router A and Serial 2/0 of Router D. Configure SVCs and XOT.

1. Configure Router A:

   # Configure basic X.25.

   <RouterA> system-view
   [RouterA] interface serial 2/0
   [RouterA-Serial2/0] link-protocol x25 dte ietf
   [RouterA-Serial2/0] x25 x121-address 1
   [RouterA-Serial2/0] x25 map ip 1.1.1.2 x121-address 2
   [RouterA-Serial2/0] ip address 1.1.1.1 255.0.0.0
   

2. Configure Router D:

   # Configure basic X.25.

   <RouterD> system-view
   [RouterD] interface serial 2/0
   [RouterD-Serial2/0] link-protocol x25 dte ietf
   [RouterD-Serial2/0] x25 x121-address 2
   [RouterD-Serial2/0] x25 map ip 1.1.1.1 x121-address 1
   [RouterD-Serial2/0] ip address 1.1.1.2 255.0.0.0
   

3. Configure Router B:

   # Enable X.25 switching.

   <RouterB> system-view
   [RouterB] x25 switching
   

   # Configure local X.25 switching, specifying packets to X.121 address 1 to pass through Serial 2/0.

   [RouterB] x25 switch svc 1 interface serial 2/0
   

   # Configure XOT switching, specifying an X.25 switching route to the XOT channel.

   [RouterB] x25 switch svc 2 xot 10.1.1.2
   

   # Configure Serial 2/0.

   [RouterB] interface serial 2/0
   [RouterB-Serial2/0] link-protocol x25 dce ietf
   [RouterB-Serial2/0] quit
   

   # Configure interface Ethernet 1/1.

   [RouterB] interface ethernet 1/1
   [RouterB-Ethernet1/1] ip address 10.1.1.1 255.0.0.0
   

4. Configure Router C:

   # Enable X.25 switching.

   <RouterC> system-view
   [RouterC] x25 switching
   

   # Configure local X.25 switching, specifying packets to X.121 address 2 to pass through Serial 2/0.

   [RouterC] x25 switch svc 2 interface serial 2/0
   

   # Configure XOT switching, specifying an X.25 switching route to the XOT channel.

   [RouterC] x25 switch svc 1 xot 10.1.1.1
   

   # Configure interface Serial 2/0.

   [RouterC] interface serial 2/0
   [RouterC-Serial2/0] link-protocol x25 dce ietf
   [RouterC-Serial2/0] quit
   

   # Configure interface Ethernet 1/1.

   [RouterC] interface ethernet 1/1
   [RouterC-Ethernet1/1] ip address 10.1.1.2 255.0.0.0
