Tim, Hence the "might". I worry when people start throwing around terms like routing in the home that they don't understand the complexities of balancing the massive CPE installed base, technical features, end user support, ease of installation & managemenet, and (perhaps most importantly) the economics of mass adoption. This one of the choices that made DSL deployments more complex and expensive than DOCSIS cable deployments which in turn caused the CEO of AT&T to say their entire DSL network is obsolete. http://goo.gl/exwqu On 8/10/2011 12:57 PM, Tim Chown wrote:

Neither of these are true, though in the future we _might_ have deployable technology that allows for automated routing setup (though I very seriously doubt it) in the home. Layer 2 isolation is both easier and more reliable than attempting it at layer 3 which is isolation by agreement, i.e. it doesn't really exist. Well, there is some new effort on this in the homenet WG in IETF.
For snooping IPv6 multicast it's MLD snooping rather than IGMP. We use it in our enterprise since we have multiple multicast video channels in use.

Bridging eliminates the multicast isolation that you get from routing.
This is not a case for bridging, it's a case for making it possible to do real routing in the home and we now have the space and the technology to actually do it in a meaningful and sufficiently automatic way as to be applicable to Joe 6-Mac.
