DLSw v2.0 configuration example

As shown in Figure 81, Router A is DLSw v2.0 capable, connected with an IBM host. Router B and Router C are DLSw v1.0 or DLSw v2.0 capable, connected with PC1 and PC2, respectively. CISCO is a DLSw-capable router of Cisco, connected with PC3. All the DLSw routers listen to the multicast address 224.0.10.0. Enable the IBM host to communicate with all SNA hosts.

1. Configure Router A:

   # Configure bridge set 1.

   <RouterA> system-view
   [RouterA] bridge enable
   [RouterA] bridge 1 enable
   

   # Add Ethernet 1/1 to bridge set 1.

   [RouterA] interface ethernet 1/1
   [RouterA-Ethernet1/1] bridge-set 1
   [RouterA-Ethernet1/1] quit
   

   # Enable multicast.

   [RouterA] multicast routing-enable
   [RouterA] interface ethernet 1/0
   [RouterA-Ethernet1/0] pim dm
   [RouterA-Ethernet1/0] igmp enable
   [RouterA-Ethernet1/0] igmp static-group 224.0.10.0
   [RouterA-Ethernet1/0] quit
   

   # Configure local DLSw peers, and allow a remote peer that is not preconfigured to initiate a TCP connection and establish dynamic peer relationship.

   [RouterA] dlsw local 1.1.1.1 permit-dynamic
   

   # Enable DLSw multicast, set the maximum number of explorer retries and specify a local bridge set.

   [RouterA] dlsw multicast interface ethernet 1/0
   [RouterA] dlsw max-transmission 3
   [RouterA] dlsw bridge-set 1
   

2. Configure Router B and Router C:

   Before configuring Router B and Router C, first identify which DLSw version they support. If they are DLSw v2.0 capable, the configuration is similar as on Router A. If they are DLSw v1.0 capable, remove the multicast and explorer frame retransmission part from the configuration.

   For the configuration on the Cisco router, see Cisco documentation.
