Yes, probably a bug introduced by arp-v2, I will investigate and get back to you. -- Qing -----Original Message----- From: owner-freebsd-net_at_freebsd.org on behalf of Christian Weisgerber Sent: Sun 12/21/2008 7:15 PM To: freebsd-net_at_freebsd.org Subject: NDP breakage in -CURRENT Something seems to be wrong with IPv6 neighbor discovery. FreeBSD lorvorc.mips.inka.de 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Sat Dec 20 17:46:35 CET 2008 naddy_at_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=YES 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. Fallout from arp-v2? -- Christian "naddy" Weisgerber naddy_at_mips.inka.de _______________________________________________ freebsd-net_at_freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscribe_at_freebsd.org"Received on Mon Dec 22 2008 - 04:50:05 UTC
