Questions about Comcast Business Delegated Prefixes
It's my understanding that DHCP-PD is only responsible for doling out IPv6 prefixes to routers which ask for them, and generally does nothing about the routing of those prefixes, leaving the routing up to the implementer.
I'm wondering how Comcast implements the routing side? Is there a standard setup which comcast uses? Do we use routing protocols like RIPvng? Or is there some convention (routes just to shoved through the router through which the req came from?) Or can you use ICMPv6 Route Announcements that the cable modem will honor?
On the CGA4131COM, it seems to just presume that the delegated prefix is just on the inside LAN interface (the entire /56).
