Please describe all benefits and detriments of using more than /30 subnet on SP PE. Some good links will be very useful for me.
Don't know all, but have you see the arp tables on a PE router? Have you seen some of the crazy things devices other than routers can do on ethernet?
Good point. We allow VPN users to have up to a /29 directly connected. Any more than that and we require a CE router. Important for scaling when you have PEs aggregating 10k or 20k customer interfaces. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
