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 comple= ting 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 >=20 > Following on from what I write about CARP, I've noticed another strange > thing happening with IPv6.
