If you're asking whether you can switch MPLS traffic, then yes, that's
no problem. And the switch doesn't need to understand MPLS to switch
Ethernet-encapsulated MPLS packets. We have a few places where P-to-P
MPLS connections are switched VLANs running through some C3560s.

Keep an eye out for MTU related problems though.
