Hi, I have two sites connected via fiber (10km apart). SiteB uses SiteA for it's WAN (internet) connection. They both have different VLANs on either side of the connection. I want to bring another building online at SiteB, but connect it on vlan 200 from SiteA. Is there a way to extend vlans across sites with different VTP domains, perhaps by routing them. See diagram for topology.
