Hi

Ideally members of different vlans would not interect with each other.

But in your case, you need to enable communications between your server vlan and user vlans.This can be achieved by implementing Intervlan routing between all your vlans.But this will enable communication between your user vlan too.So, to restrict that you can apply access-lists to allow communication with server vlans and denying everything else.

Remember that for Intervlan routing, you need to dedicate a seperate block of IPs for each vlans.

Hope that will help.

Dear JD,

Thank you for your immediate reply. Thanks for the info but if you can give me a sample configuration or links that I could start with would be more helpful.

Thank you

HI

This will work only on a L3 switch.

For eg you have 2 user vlans : vlan 10 and 20

There is a server vlan 100

for intervlan routing :

int vlan 10

ip add 10.0.0.1 255.255.255.0

ip access-group 111 in

int vlan 20

ip add 10.0.1.1 255.255.255.0

ip access-group 111 in

int vlan 100

ip add 10.1.1.1 255.255.255.0

access-list 111 permit ip any 10.1.1.0 0.0.0.255

access-list 111 deny any any
