A VLAN is L2, has a tag and can contain physical interfaces. Acts similar to a L2 switch. A Vlan interface is L3, has a tag that matches one of the VLANs and provides a point where an IP can be assigned and can participate in routing. An Ethernet interface can have subinterfaces with tags that match the VLANs. 11 Things About Using A Transparent or Layer 2 Firewall Here are my notes both for and against Layer 2 Firewalls. Keep in mind that L2 Firewalls are most common in data centres and are typically retrofitted to provide security. In general terms, I would only recommend using L3 firewalls for any new design or new build. Layer 2 vs. Layer 3 MPLS | GCOMM Mar 16, 2012 10.6 Build a LAN-to-LAN VPN (Using L3 IP Routing

Implementing MPLS Layer 2 VPNs - Cisco
Layer 2 MPLS VPNs, or VPLS (virtual private LAN service), offers a “switch in the cloud” style service. VPLS provides the ability to span VLANs between sites. L2 VPNs are typically used to route voice, video, and AMI traffic between substation and data center locations. Layer 3 VPN (VPRN) Layer 2 Ethernet or Layer 3 IP VPNs? - YouTube Apr 26, 2010
