Hi Pros, Thinking of Virtual CPE as a service to enterprise customers where CPE is virtualized in POP and low cost device in customer premises as a simple bridge device which bridges the traffic to v-CPE in POP. This is to have cost advantage to customers and in POP, any different service can be easily enabled as required by customer solution - firewall, routing, wan acceleration etc.
But the challenge is the backhaul from customer premise to our POP is on Metro-E Layer 2 switched network. Hence the Layer 2 cannot be extended on Metro-E which can cause significant ARP broadcast as the gateway for customer LAN is in v-CPE in POP. Couple of queries: a. Is there a way to configure MAC-in-MAC between a bridge device in customer premises and a MAC-in-MAC gateway till our POP, so that Metro-E backhaul can only see outer MAC address? Can this option be possible, If yes, what would be cost advantage gained when the bridge device costing is low? b. Sure other providers would be doing this kind of solution, but how do they achieve this and overcome the challenges of LAN extension over shared Metro-E L2 switched network.
