This would not work with "multi-hop BGP" sessions :-) Thanks, I realize that, especially with iBGP. However for directly connected eBGP peers, the question still stands. What side effects if any are there? Why is the default 64 and not some other number like 255... I am sure the answer is out there, I just need to find the question so I can cram it into google ;-) Perhaps this is a better topic for freebsd-net ? ---Mike
