Setup: Cisco router with multiple VLAN's configured on it.
How can you prevent 2 VLAN's communicating with eachother? Normally I would do this with ACL's like this:
access-list 102 deny ip 22.214.171.124 0.0.0.255 126.96.36.199 0.0.0.255 access-list 102 deny ip 188.8.131.52 0.0.0.255 184.108.40.206 0.0.0.255 int vlan 1 ip address 220.127.116.11 255.255.255.0 access-group 102 in int vlan 2 ip address 18.104.22.168 255.255.255.0 access-group 102 in
This however is not handy when dealing with lot's of VLAN's configured on a router. Any suggestions of tweaking this or using an alternative to improve scalability?
