Configuration example for transparent bridging over FR
Network requirements
As shown in Figure 111, two LAN segments, LAN 1 and LAN 2, are attached to Router A and Router B, respectively, which are interconnected over FR. Configure the two routers to enable transparent bridging over FR between the two LAN segments.

Configuration procedure
Configure Router A:
<RouterA> system-view [RouterA] bridge enable [RouterA] bridge 1 enable [RouterA] interface ethernet 1/1 [RouterA-Ethernet1/1] bridge-set 1 [RouterA-Ethernet1/1] quit [RouterA] interface serial 2/0 [RouterA-Serial2/0] link-protocol fr [RouterA-Serial2/0] fr interface-type dce [RouterA-Serial2/0] fr dlci 50 [RouterA-Serial2/0] bridge-set 1 [RouterA-Serial2/0] fr map bridge 50 broadcast
Configure Router B:
<RouterB> system-view [RouterB] bridge enable [RouterB] bridge 1 enable [RouterB] interface ethernet 1/1 [RouterB-Ethernet1/1] bridge-set 1 [RouterB-Ethernet1/1] quit [RouterB] interface serial 2/0 [RouterB-Serial2/0] link-protocol fr [RouterB-Serial2/0] fr interface-type dte [RouterB-Serial2/0] bridge-set 1 [RouterB-Serial2/0] fr map bridge 50 broadcast
