Here I show the commands to create a MPLS/VPLS network with transparent bridging. Each PC in the diagram are on their own private LAN. Pretty cool setup if you use Mikrotik routers. OSPF/MPLS/LDP/VPLS is all setup. It can be hard to find information to do this on Mikrotik routers. So here it is. Plain and simple. Each PC is connected to ETH2 on the Mikrotik’s. This is built in GNS3, using the GNS3 VM. Basically, it is all about the bridge. Put both the ETH interface and the VPLS interface in the bridge you create and that’s it!
