Bridging multiple LANs across a single link?

Is it possible to bridge multiple LANs across a single link? Scenario - two distinct LANs bridged to two LANs at a remote site via a single high-speed WAN link. Only two routers are involved. Can I use logical subinterfaces on the high-speed fibre WAN link and assign bridge-group numbers that correspond to the two LANs to them (ie.to "multiplex" bridge-groups)?

Router 1

LAN1-e0 LAN2-e1

yes,

you can do such kind of think. you can use the multiple logical subinterface and then assigning them in to the bridge-group by using the same command.

rate this post if it helps

As Devang said, it can be done. You can assign tags to your Ethernet interfaces by creating sub-interfaces on your LAN side and then bridge the LAN/WAN interfaces.

Thanks.
