There are many situations where no per-VLAN-forwarding database could lead to problems. AFAIK all SVIs on Catalyst switches (e.g. 6500) use the same MAC address. Likewise all subinterfaces on a 7200 share the MAC address of the primary interface. I know for certain that models 3550 (now EoL), 3560, 3750 and 6500 behave as you expect with per-VLAN FDB. Extreme switches must be made for some very special networks. :-) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
