Configuring LAN-to-LAN DLSw

As shown in Figure 77, DLSw works in a LAN-LAN environment. Configure DLSw on Router A and Router B to enable communication between an IBM host and an SNA host over the Internet.

1. Configure Router A:

   # Configure interfaces on Router A to make sure that the local DLSw peer 1.1.1.1 and remote peer 2.2.2.2 can reach each other. (Details not shown.)

   # Configure DLSw on Router A.

   <RouterA> system-view
   [RouterA] bridge enable
   [RouterA] bridge 5 enable
   [RouterA] dlsw local 1.1.1.1
   [RouterA] dlsw remote 2.2.2.2
   [RouterA] dlsw bridge-set 5
   [RouterA] interface ethernet 1/0
   [RouterA-Ethernet1/0] bridge-set 5
   

2. Configure Router B:

   # Configure interfaces on Router B to make sure that the local DLSw peer 2.2.2.2 and remote peer 1.1.1.1 can reach each other. (Details not shown.)

   # Configure DLSw on Router B.

   <RouterB> system-view
   [RouterB] bridge enable
   [RouterB] bridge 7 enable
   [RouterB] dlsw local 2.2.2.2
   [RouterB] dlsw remote 1.1.1.1
   [RouterB] dlsw bridge-set 7
   [RouterB] interface ethernet 1/0
   [RouterB-Ethernet1/0] bridge-set 7
   

After this configuration, the two SNA LANs across the Internet are interconnected.
