Private Line config trouble

[matthew_keffer]

I am trying to configure a Comcast layer 2 Ethernet Private Line between two sites and can't figure out what I'm doing wrong.  We have disparate subnets at the sites and use local DHCP servers, so extending the L2 is not an option.  

I have an ICX6450 on one side and an ICX7250 on the other side.  Both are running router code and I have reached my wits end on this. 

Any direction would be appreciated.
