Comcast Metro Ethernet Setup

[cisco]

We have one customer with one ASA and one 3750 switch in headquater. 6 1801 Routers in 6 branches.

All connected via MPLS/BGP provided by ATT. And it was terminated at one port on 3750.

We plan to replace that with Metro Ethernet Hub/Spoke topology since the customer mentioned each office never talks to each other. Later on we found they have IP phones do need to talk with each other at branches.

Question - can we still use the MetroE service but configure routing to make each office talk with each other and how that would work?? I would assume some routings on 3750.

Any info is appreciated. thanks!

Hi Ben,
It will work for sure since this is what ( in a much more complex scenario) we are implementing in our company since ab few months. Just take care of defining data and voice subnets as technically unrelated so to be free implementing very flexible and easy to manage routing policies. Is ATT providing L3VPN or what?

Hope to help
Alessio
