To the customer, it still should look like one Ethernet segment so they don't have to do multihop. Maybe still have a couple of these locations and multi-home their BGP sessions. They'll still get all the benefits of your fancy network, and suitable hardware will probably be a lot less expensive if you only have to buy a couple big routers for your BGP sessions instead of fitting it all into a large expensive switch. Anyway, I can't find anything in the low end of the Cisco line that offers that much RAM. No Catalyst gear, for instance. You'll likely need to look a bit higher up in the "router" space, honestly. Probably not "Cisco CRS" high, but this could be a fairly pricey project, which is why I'm trying to think of alternatives. David Smith MVN.net
