TCP/IP header compression protocol application

As shown in Figure 148, two routers are directly connected.

1. Configure RouterA:

   # Configure the link layer protocol of Serial 2/0 as X.25, and configure the interface to operate in DTE mode.

   <RouterA> system-view
   [RouterA] interface serial 2/0
   [RouterA-serial2/0] link-protocol x25 dte ietf
   

   # Assign an x121 address for the interface.

   [RouterA-serial2/0] x25 x121-address 1001
   

   # Assign an IP address for the interface.

   [RouterA-serial2/0] ip address 16.16.16.1 255.255.0.0
   

   # Enable TCP/IP header compression.

   [RouterA-serial2/0] x25 map compressedtcp 16.16.16.2 x121-address 1002
   

2. Configure Router B:

   # Configure the link layer protocol of Serial 2/0 as X.25, and configure the interface to operate in DCE mode.

   <RouterB> system-view
   [RouterB] interface serial 2/0
   [RouterB-serial2/0] link-protocol x25 dce ietf
   

   # Assign an X.121 address for the interface.

   [RouterB-serial2/0] x25 x121-address 1002
   

   # Assign an IP address for the interface.

   [RouterB-serial2/0] ip address 16.16.16.2 255.255.0.0
   

   # Enable TCP/IP header compression.

   [RouterB-serial2/0] x25 map compressedtcp 16.16.16.1 x121-address 1001
   

Ping Router B from Router A to verify that the two routers can reach each other.
