Question regarding Metro Ethernet setup and routing between sites.
Your are getting Metro Ethernet service from your ISP (AT&T). The ISP is providing "non-q-in-q" ME service. You have the "hub" main headquarters site and several remote sites. The connectivity between the sites will appear as one broadcast domain (I am assuming).
Each site is subnetted with it’s own ip addressing scheme. The hub site will be the aggregate and have a router. The remote sites will have routers.
At the main site will I be able to create sub-interfaces (for each site) and associate them with a dot1q tag in the same L3 subnet for point to point connectivity as the remote site routers? The main site and remotes would be attached to the same native vlan, but then have sub-interfaces for the point to point or hub to remote site connectivity. Will this work? Or do I create one L3 address at the hub and then for each remote router assign a L3 address from the same L3 subnet as the hub?
Thanks
