Hi Ben, That case is covered by things like ARIN's multiple discrete networks policy which permit an ISP /32 or end-user /48 for _each_ distinct network. There are plenty of addresses in IPv6. You should be break up a /32 for traffic engineering purposes, not for the sake of handling multiple disconnected sites. And when exercising TE, you can offer a covering route and expect the network as a whole to still function regardless of other folks' suballocation filtering. Regards, Bill Herrin -- William D.
