12:08:27 was when the hold timer expired, so it actually lost communications with the neighbor 15 secs before that.

Hi there,
I hope this output taken from the rfc 3815 Will help you
pathVector(4) -- Loop Detection is supported by
Path Vector only.
hopCountAndPathVector(5) -- Loop Detection is
supported by both Hop Count
And Path Vector.
Since Loop Detection is determined during
Session Initialization, an individual session
may not be running with loop detection. This
object simply gives an indication of whether or not the
LSR has the ability to support Loop Detection and
which types."
RFC 3815 page 9.
I hope this helps
Alessio
