Very well put, but not exactly what happens with HNCP, which specifies things fairly precisely for IPv4. (A good thing, IMHO.) > In this case... what's do we get from doing src/dest routing for IPv4 > given that a host only ever has one IPv4 address? In a typical Homenet, we're not doing source-specific for IPv4. HNCP elects a single NAT router that delegates 10/8. HNCP is a little vague about whether all NAT gateways announce a (non-specific) IPv4 default route -- hncpd/OpenWRT pushes traffic through all NAT gateways, while by default shncpd pushes all traffic through the router doing the delegation. (More precisely, HNCP says which routers must announce routes into the routing domain, but doesn't specify whether any other routes can be announced. Hncpd/OpenWRT announces all available routes, while shncpd performs careful filtering in order to only announce the minimal set of routes. A clued administrator can add filtering rules to announce additional routes, of course, and since babeld's config file format easy to generate, this could be a point-and-click configuration item.) -- Juliusz _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
