BgpReasonNotBest
If bgpNlriPrefixBest is 'true', then this field is set to
'routeIsBest'. Otherwise, it reports the stage in the
decision process when the route was determined to be
non-best.
This is the reason that the route was discarded from the
decision process. There may be other reasons why this route
is less preferred than the best route.
