Karen, We are currently working on rolling out Martini L2 Ethernets over MPLS. There are two Cisco ways to do Ethernet over MPLS.
The first and most commonly used method uses VC 0x0004 as defined in draft-martini-l2circuit-trans-mpls. It is used to transport individual .1q vlans, which if I read your message correctly is what you want to do. It's configured like this: PE router Int gig 1/1.100 Encap dot1Q vlan-id Mpls l2transport dest-ip vc-id The second and newer EoMPLS technique is support of VC 0x0005. It has just recently been introduced in (the quite buggy on 7500s) release of 12.0.24S. This technique supports port to port Ethernet trunking allowing many vlans to flow over the same physical port and letting you trunk Ethernet switches through the network. It sounds like what you want is the first technique. One word of caution though. Every Ethernet device the communicates with the PE router will be in said routers ARP table. Be careful. That being said this is some awesome technology. I'm definitely a big fan. Good Luck and let me know how your MPLS implementation goes.
