[c-nsp] ME3600x L3VPN MPLS problems with 15.3.2S

[Jason Lixfeld]

I have seen this on a bunch of different ME3600s across my network from 15.2 all the way up to and including 15.3.  I haven't actually been able to readily duplicate this, so I'm very intrigued that you both are able to replicate it, seemingly at will. 

I actually have a call scheduled at 11am with a fleet of Dev engineers from India and SJ.  I will be bringing this up with them, because this is one of our big mystery issues that we can't replicate but have seen multiple times.

Can either of you share a *complete* device config? (Passwords, SNMP comma and IPs sanitized, if required).  I'd be grateful and hopefully with your help we'll be able to put a bugid to this issue.

Thanks.
