Well in my network Intervlan is working perfectly. We have about 80 switches in a network, includes all Access as well as Distribution. Now I have a case in hand where we have to stop all Vlan 20 users from accessing all vlan 30 users. And they in curent scenario able to access internet which should nopt get hampered. Well these both vlans are present on almost 30 odd switches and they all are getting connected through Core switches. How can I acheieve it, can we discuss all the possible solutions for the same irrespective of network. In general if I want to achieve this how can i do it ?
Please help me on this.
Private vlans and VACL's are generally used for traffic between members of the same vlan not between members of different vlans.
You could use a firewall instead but it's the same principle.
