I have a cisco 4507 CORE switch on which i want to implement routing and vlans through vtp.I Have the 3750 distribution switch (connected to the core) on which there are several vlans.
How can i prevent the vlans from talking to each other ?
I know of port protection but since there is a layer 3 device it will not work.
As of private vlans they only work in vtp transparent mode.
Since i am using dhcp i can not use vlan access map.
I can not use the switchport allowed vlan since they are on the same switch.
Any idea will be great
Okay, your best bet is to use private vlans. Yes you will need transparent mode but with only 5 vlans i'm not sure that is really such an issue.
If you really want to stop every user talking to every other user within the same vlan you may want to ask why this is the case ie. you may want to reconsider some of the design setup.
