Hi community, I'm having this situation where we are migrating from a 7500 router to an ASR1004. The 7500 is working perfectly and establishing all of it's adjacencies with no problem whatsoever, but when we change the router to an ASR1004 we are experiencing problems in the way that one of the peers is not sending the routing update to it, refreshing the routes in the routing table every one minute. The configs are shown below:

I'm really shooting arrows here to see if I can get to the root of this problem. Am I hitting a bug? is this normal behaviour? is the problem in the remote peer? if so then why does it work with the first router?
Summarizing:
1. Adjacency for this neighbor lasts for one minute (hello timer or hold down didn't solve the issue)
2. Routes in routing table refresh every one minute.
3. Remote router has too many routes pending
Hope you guys can help me here.
Thank you
