Running FreeBSD 7.1, testing Duplicate Address Detection, when I intentionally set duplicate Link Local Address, dmesg shows:
em1: DAD detected duplicate IPv6 address fe80:4::217:a4ff: fe51: fb0d: NS in/out=0/3, NA in=1
em1: DAD complete for fe80:4::217:a4ff: fe51: fb0d - duplicate found
em1: manual intervention required
em1: possible hardware address duplication detected, disable IPv6
After that all IPv6 traffic seem to be off, ifconfig down/up didn't work.
Any idea how to turn IPv6 back on? Thanks!
