FreeBSD lorvorc.mips.inka.de 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Sat Dec = 20 17:46:35 CET 2008 = naddy@lorvorc.mips.inka.de:/usr/obj/usr/src/sys/GENERIC amd64 This box is on a network that has IPv6. No exciting configuration, just ipv6_enable=3DYES and ipv6_defaultrouter and ipv6_ifconfig_nfe0 for a manually configured address. IPv6 with other hosts on the network and beyond works. However, clearing the NDP cache (ndp -c) kills IPv6 connectivity. The cache remains empty. tcpdump shows that neighbor solicitations are sent and advertisement received, but these replies seem to be ignored. ndp -a shows that no entries are added to the cache. This is a new problem.
