I just tried it with ipv6 address on my 12.4T dyanmips setup and it didn't like the overlapping addresses. Someone suggested to me, off-list, that I could use BVI. I seem to have some memory of BVI being quite CPU intensive but it's been a *long* time since I looked at it. Does anyone know if there's any truth to that? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
