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. - jared -- Jared Mauch | pgp key available via finger from firstname.lastname@example.org clue++; | http://puck.nether.net/~jared/ My statements are only mine.
