Im trying to make sure I understand the log messages Im seeing during BGP
convergence events.  Was hoping someone could validate what the following
messages meant...



added - A route was received from the peer listed and added to the RIB

added [best] - A route was received from the peer listed and added to the
RIB and is now the best option in the RIB

removed - A route originally received from the peer listed was removed

removed [replaced] - Im not clear on what this one actually means

ignored - A route was received from the peer listed but ignored.  Does
ignored in this case mean that it wasn't put in the RIB?  If so - does that
imply that it was filtered?



Is there a list of what all these log messages mean?  Also - I assume that
the < and > signify direction - that is received or sent but clarification
on that would be good as well.



Thanks!
