Configuration example for transparent bridging over PPP
Network requirements
As shown in Figure 109, two LAN segments, LAN 1 and LAN 2, are attached to Router A and Router
B, respectively, which are interconnected over PPP. Configure the two routers to enable transparent
bridging over PPP between the two LAN segments.

Configuration procedure
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 ppp
[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 ppp
[RouterB-Serial2/0] bridge-set 1
Configuration example for transparent bridging over MP
Network requirements
As shown in Figure 110, two LAN segments, LAN 1 and LAN 2, are attached to Router A and Router
B, respectively, which are interconnected over MP. Configure the two routers to enable transparent
bridging over MP between the two LAN segments.
