Unanswered Question

Does anyone know any way to create a common subnet in two separate datacenters with or without MPLS connectivity.

I have this problem too.

That depends on what you have connecting the two data centers. The most generic way I can think of is to create a GRE tunnel between the two data centers and bridge your VLAN over it. If you have a Metro Ethernet or wireless connection between the data centers, you can do 802.1q trunking and share a VLAN between the data centers that way.

Thanks for the response! The datacenters are connecting via AVPN MPLS. Any experience with this scenario?
