I am conecting my two offices with dark fiber. At the same time both sites are connected with MPLS.I want to pass Vlans between these two sites. More prcisely I would like to have for example Vlan 100 in site A and in site B. I configured dark fiber connection as Layer 2. VTP distributed all VLANS accross. When tracing from site A to site B traffic passes through MPLS and not through dark fiber. Right now I am able to route between these two networks if dark fiber is configured as Layer3. Do I need to configure Inter Vlan Routing? If yes, can someone give me an example please. I am attaching two diagrams. First is showing present connection, second is showing desirable connection.
Any help would appreciated.
