No. Since it only exists on one port. But this is a good way to test it by the way: start a ping -b 255.255.255.255 from a host, and look for the mac-adddress in the table: it should exist on the host port, and on the router port, but in different vlans, if that really happens, and not transient, but rather static, then you have an IVL. In this case the mac-address of the router is: 0002.b326.43db. But what you actually want to have in setup 1b is that 000b.5d9c.5982 exists in vlan 3 port 14, and in vlan 2 and 1 port 16. The same for: 0015.c56e.c05f, it should exist in vlan 2 port 15, and in vlan 1 and 3 port 16. But on an svl switch, there can only be one mac->port relation.

In your case I would really consider proxy-arp and routing. >From the hosts point-of-view, all hosts are in the same network, but your router knows better... :-). http://lartc.org/howto/lartc.bridging.proxy-arp.html says something about it. -- begin LOVE-LETTER-FOR-YOU.txt.vbs I am a signature virus.
