MPLS Tunnel Traffic Question

[wrainwater]

I work at a company where we have two MPLS tunnels in use. One tunnel pushes traffic over the internet while the other seems to only push layer 2 traffic to our six sites. My question is is an MPLS tunnel consider Layer 3 or Layer 2? Trying to understand the logic of how everything is routing here. Our internal traffic seems to traverse out the "Layer 2" tunnel while out internet traffic going out the "Layer 3".  Anyone else seen a similar network architecture?

Yes that can one of the possible solution. One for Internet and one use for your Branch office. where the branch office come to head office and go to internet. (that is the network flow as below :

Branch office ----L2 MPLS------HO -----L3 MPLS  for internet
