How to stop Cisco 1721 from automatically routing between Vlans
Posted on 2008-09-30
I have a Cisco 1721 with a 10bt WIC in it.
I have trunking configured on the fa0 interface and PAT configured on the e0 interface. I have 2 vlans trunked with dot1q to the fa0 interface
PAT/DHCP are enabled to serve both vlans.
My question is, how do i prevent Vlan1 from pinging/accessing Vlan2 and vice versa?
Seeing as how both vlans are in my connected routes in show ip route, the router just assumes it should route to them, but I want them segmented, yet still able to access the internet through e0
