How to control traffic flow between vlans - with ACLs?

Hi gents,

When you need to allow only certain "clients" to access a VlanX.
And the way those clients could get to VlanX (or any other Vlan) is via VE in/on VlanZ - think of that VE as the gateway for those "clients" to get to other Vlans.

Would you have to construct ACLs or is there another (simpler) way?

many thanks, L.

Pawel,
Depending on the platform (i.e. Exos, VSP, NetIron, Network OS) there may be other options you can use to control flow of L3 traffic from one network to another on a particular system. However, as a general rule of thumb if we are just talking theory you are really limited to using ACL's and or depending on the L3 IGP you are using possibly using Route Maps and prefix lists as well.
