Hi,

You can search several things in Google.

The most important part is that in L2 MPLS solution it is like overlay MPLS. The Service Provider need not to to participate in customer routing.

However in the L3 MPLS solution is peer-to-peer VPN. The MPLS Service Provider will participate for CE-PE routing.

L2 MPLS is ideal for Point to Point link required where as L3 is in general any-to-any connectiviy - best for Hub and spoke.

Cheers!

Sumesh, there is no difference in the position of the shim. As the L2VPN is also a part of your frame mode MPLS.

The shim carries an extra label for the VC though.
