Oops, sorry about that. I missed this question. It is related to "So what happens when there are multiple default routes?" as well. PIM-(SS)BIDIR does the routing inside the home network. The only route that BIDIR uses is the one to the RP-Address, which is inside the home network. So it does not uses default routes. The assumption is that the user will want to receive traffic from the ISP. To do so, it needs to subscribe first (e.g. using MLD) on one of the WANs. One problem is that you don’t know which WAN. The solution used here is to subscribe on all WANs. This subscription/forwarding is the proxy part. Proxy *controller* is the process that allows routers to ask border routers to subscribe to given groups. In the HNCP case, a single router is elected on the RP-Link. This router will have a knowledge of the home-wide-membership-state and will reflect that state by « asking » (through TCP connexions) all border routers to subscribe to those groups. I hope it is clear enough, - Pierre _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
