Network requirements

As shown in Figure 143, 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 PVCs and XOT.

Configuration procedure

  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 1111
    [RouterA-Serial2/0] x25 vc-range in-channel 10 20 bi-channel 30 1024
    [RouterA-Serial2/0] x25 pvc 1 ip 1.1.1.2 x121-address 2222
    [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 2222
    [RouterD-Serial2/0] x25 vc-range in-channel 10 20 bi-channel 30 1024
    [RouterD-Serial2/0] x25 pvc 2 ip 1.1.1.1 x121-address 1111
    [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 Serial 2/0 and an XOT route.

    [RouterB] interface serial 2/0
    [RouterB-Serial2/0] link-protocol x25 dce ietf
    [RouterB-Serial2/0] x25 vc-range in-channel 10 20 bi-channel 30 1024
    [RouterB-Serial2/0] x25 xot pvc 1 10.1.1.2 interface serial 2/0 pvc 2
    

    # Configure 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 Serial 2/0 and an XOT route.

    [RouterC] interface serial 2/0
    [RouterC-Serial2/0] link-protocol x25 dce ietf
    [RouterC-Serial2/0] x25 vc-range in-channel 10 20 bi-channel 30 1024
    [RouterC-Serial2/0] x25 xot pvc 2 10.1.1.1 interface serial 2/0 pvc 1
    

    # Configure Ethernet 1/1.

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