You could always use a VLAN MAP to isolate traffic on the same VLAN sort
like Private VLANS on a 3550. Keep in mind though this will only isolate
Layer-3 traffic and NOT Layer-2.
On another note has anyone tried routing private VLANS accross switches?
i.e. You have 4 servers and two switches, and a firewall. 2 servers
pluged into each switch and a connection exist between the swithes. All
of the servers are in the same subnet however you would like 2 of the
servers to be in 100% isolated layer-2 broadcast domains and the other
two servers in the same community and can talk to each other. All
servers should be able to talk to the PIX firewall in switch a? Is this
possible? I am guessing due to the restriction of communities only on
4000 and above it can be done? I guess you could do it with a 4000 and a
3550 if you grouped them properly with only edge features?
Ideas?
