[j-nsp] BGP over GRE

[Scott Morris]

How are you reading that as the other end?  BGP SEND means that my end is
sending it out, no?  The administrative clearing is when I issued a clear
command on the Juniper side.  The Cisco logs are only showing and
authentication mismatch (whether we have authentication configured or not).

I'll try to get access to the far end router and see if I can get more
details from the Cisco side, but there doesn't appear to be much of anything
there.

Ah, this is a new error.  It's saying that the *far end* is closing the
session.  You'll need to look at the logs on the far end to see what the
problem might be :-)
