I haven't modified the ndp related code for quite a long time, but recently have seen some postings regarding incomplete ndp entries (still catching up on emails). Changes committed in the past year or so were related to locking and memory leak, not functional updates. I have seen this issue with ARP, where incoming ARP requests are not completing the entries until an explicit outgoing packet is generated right after the system boots. Email me when you recreate the problem. --Qing > -----Original Message----- > From: owner-freebsd-stable@freebsd.org [mailto:owner-freebsd- > stable@freebsd.org] On Behalf Of Pete French > Sent: Wednesday, April 13, 2011 3:14 AM > To: freebsd-stable@freebsd.org > Subject: IPv6 / ndp taking a long time to resolve in this weeks STABLE > > Following on from what I write about CARP, I've noticed another strange > thing happening with IPv6.
