Hey Jason, I don't see any LCP Conf-Ack for the LCP request sent by Adtran, & as you pointed the endpoint discriminator option block received from the peer are truncated with a LCP config-reject message.
So what Junos version router is loaded with? Check if you are hitting PR/97169 (available on website) Thanks & Regards, Tarique A.

The Juniper appears to be rejecting an LCP configuration option including a MAC address received from an Adtran. I haven't been able to find a reference in RFC 1661 indicating that "End-Disc" is a valid option. This is the second time we've seen this issue and I'm not sure if I'm digressing from the real issue or if I should continue to pursue this. The following debugs were from the same ~20 second period. The Adtran never indicates that it has received an LCP message, while the Juniper both transmits and receives. In the interest of brevity, I have removed all but two cycles of configure reject messages from the Juniper monitor traffic interface detail output.
