I guess all those root servers that use the same asn
but connect to different networks (anycast) should get shut down
quickly.
This is a part of networking life today in the v4 space,
and without any current changes, it will (is) the same in v6
routing as there is nothing different except a few more bits 32 => 128.
No new routing protocol, nothing, except this shim6 thing
which people don't seem interested in because it means network
operators can't do the traffic engineering they need to.
