<RCC>Maybe so, but it seems complex. It strikes me L3 routing is a more pragmatic approach, considering that is what is being done in, for example, ROLL, with simple one-interface routers.</RCC>On Aug 3, 2011, at 21:03 , Robert Cragie wrote:L2 bridging is OK if you can do it but not everything looks like Ethernet frames. Not only that but if we have multi-link subnets using route-over, the router to host ratio goes up considerably. The problem space is then multi-link subnets then multi-subnet site/zone/homenets. L3 routing is the only way this is going to work in homenet.This is not strictly true. ND-proxy is an alternative.
<RCC>I don't doubt there will be a lot of issues to cover. L2 bridging is clearly simple but has clear issues beyond the common L2 frame for heterogenous subnetworks within the home, for example, with mesh wireless networks with sleepy nodes. This to me seems like the opportunity to take the bull emerging from your bag of cheese (how did it get in there?!) by the horns.</RCC>I've been told it's not a *viable* alternative--- for unspecified and possibly non-technical reasons-- but it is an alternative. I've got a big bucket of popcorn to munch while I watch this discussion play out, and I really don't have a strong opinion one way or another. My take, to the extent I have one, is that in comparison to L2-briding and ND-proxy, L3 routing on home networks will be "a bag of hurt" (to borrow a phrase from Le Grande Fromage), but if that's the direction from which rough consensus will emerge... well, okay then. Let's open up the bag.
