Comcast Metro Ethernet Network Setup

We recently changed our T1 services through AT&T over to the Comcast Metro Ethernet Network.  I have 11 locations and each location spoke to each other through a VPN I built using the Cisco RV0xx routers (All Layer 3).  

Through the Comcast MEN I was given an EDI (internet) of 50 mbs at my Corporate location and each sub location has a 10mb ENS (Layer 2 point to point).  I was able to set the WAN addressing up to receive the internet connection to Corp in the Cisco RV082 & on the RV042's for the remaining locations I set the WAN to obtain IP Automatically and those shops are online as now as well.  

The problem that I don't know how to fix with these routers is how do I configure them to be able to speak to one another?

Currently each RV0xx has it's own IP Address:
Location 1
Location 2
Location 3

I know that sub location is what they call an edge router, I just don't know which fields to change within the router and how to set up a routing table for all the location to speak to one another.  

Please help!

With 11 sites, you might want to look into a dynamic routing protocol. Your router should support RIPv2


Go to the "advanced routing" area for this configuration.

you will leave the inside IP address alone. For the outside IP address (on the ENS), you will put all the routers on the same subnet since they will be using layer 2. As recommended about, you could setup a dynamic routing protocol, especially if you will be making frequent changes. If not you could use static routing. As an example for the subnet behind router 1, you will point to router 1's outside ip.  You wont be using nating on the routers.

That is a basic high level.

So with using dynamic routing, do I keep Router 1 as the gateway and enable RIP v2 to receive and transmit as broadcast and change the other 10 routers to a router enabling the same RIP protocol?
