I have a 2921 router directly connected to an Ethernet MPLS network, one of about 10 location all configured the same. This is a new install and has been tested by the LEC to be good however, even thought the interface below indicates to be up/up we are unable to PING the peer IP address or establish a BGP session. I have chaned the speed/duplex to every combination possible and tried makeing the VLAN ID 16 native but nothing works.
Does anyone know where I might start looking for the problem?

the problem was stated as the folowing
"I too have the same issue and have tried fiddling with speed and duplex. Have also plugged a laptop into both the provider handoff and separately the router wan port and am able to ping the laptop from router and provider next hop successfully. I plug the router into the handoff and no ping / incomplete arp. I have tried configuring different router ports with same result. Have tried loopback cable with same result. Provider insists problem is our equipment. Any suggestions / ideas?"
I too have same issue, was this resolved and if so how.

So you are particularly interested in the post by tbarkhaus in June 2018. This might or might not be the same as the issues posted in July 2013 and Feb 2016. I hope that tbarkhaus is still participating in the forum and will respond about whether the issue was solved.
