The above is the number one reason against using VLANs for layer 2
transport. A second important issue to consider is management. Every
device from end-to-end where you want to deliver layer 2 transport
requires configuration if you use VLANs.
Both of the above issues are solved with MPLS. First, MPLS rides on top
of your layer 3 network giving you all the benefits of routing
protocols. Second, you only need to configure the edge device on either
side of a layer 2 virtual circuit. All the devices in-between
--including protection paths don't require additional configuration for
each virtual circuit.
