Configuration example for transparent bridging over HDLC

As shown in Figure 113, two LAN segments, LAN 1 and LAN 2, are attached to Router A and Router B, respectively, which are interconnected over an HDLC link. Configure the two routers to enable transparent bridging over HDLC between the two LAN segments.

1. 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 hdlc
   [RouterA-Serial2/0] bridge-set 1
   

2. 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 hdlc
   [RouterB-Serial2/0] bridge-set 1
