Comment 6 for bug 1930200

Looking at usecased mentioned in the RFE description, it sounds useful to me.
It looks similar to anycast in the L3 routing layer, but it is limited to local nodes.
One point I am not sure is whether we need some kind of "default" route for a "NodeLocal-IP". In the proposal, access to "NodeLocal-IP" is unreachable (as the "NodeLocal-IP" is not associated in Node-C. I see two cases: "NodeLocal-IP" must be associated in all relevant nodes or we allow some kind of "default" destination. I am not sure which is better. If we allow "default" destination, we can ensure the reachability for "IP-X" (which is configured as "NodeLocal-IP").
