I am seeking advice regarding firewall capabilities between internal VLANs. I currently have a collapsed core architecture with a single core switch (4500 series). All internal VLAN SVIs reside on the core switch. I'm using access lists to restrict interVLAN communications, but I am wondering what other options I have. The only thing I can think of is to move the VLAN SVIs to an ASA. Is that a recommended approach? Any other suggestions would be greatly appreciated.
I ask becasue we seldom see small-medium networks restricting inter-VLAN traffic. We see it sometimes on larger enterprises (with dedicated firewalls for that purpose) and increasingly in data centers separating VMs or subnets ("east-west" firewalling).
An alternative approach is separate VRF instances if the subnets never talk to one another yet share a single core.
