This is my lab. I configured OSPF for ISP and ran static route from Customer to ISP. I built a GRE tunnel from Customer 1 to Customer 2. After building the tunnel I am trying to run site to site MPLS. The LDP neighbors never come up. I am not running MPLS through the ISP.
Can anyone tell me what I'm doing wrong?

Hi
By default LDP will try and establish a TCP adjacency with the discovered neighbors highest loopback IP address. If the loopback IP address is unreachable then the adjacency will fail.
Can you reach 50.50.50.50 from 10.10.10.10 over the GRE tunnel? If not you will need to add static routes to R1 and R5 to reach the loopback interfaces over Tunnel1.

BAM! THANK YOU!!!
I configured EIGRP on both customer site and put the loop0 into the network statements and it all works now!
