Hi, I've been TAHI testing FreeBSD 7.x sources for the past couple months and over the course of my testing via the TAHI IPv6 conformance test, I changed the knob value from net.inet6.icmp6.nd6_useloopback=1 -> net.inet6.icmp6.nd6_useloopback=0 and ran into a slew of errors with the addr.p2 phase-1 TAHI tests. I was wondering if someone could describe what the beforementioned sysctl is supposed to do from a functional perspective, how it might tie into other IPv6 RFCs (if applicable), and if disabled how it would affect a system with IPv6 enabled. Thanks, -Garrett
