There's literally one command here in the docs, and it doesn't look like
you're using it. You are using one that isn't documented, too. Woo!

I'd suggest taking the 'ospfv3 1 ipv6 bfd' command out and seeing if
that still gives you an IPv6 session attempt? If in doubt, add the 'all-
interfaces' to 'ospfv3 1 bfd' & look again.
Old IOS and old hardware. Great gear at the time, but I can't imagine
anyone at Cisco will be interested in fixing it if it's not quite
working right.
The only other thing I've be interested to know is if you can specify a
pair of static link-local neighbour addresses under 'ospfv3 1 ipv6 bfd
...'? Something like fe80::1 and fe80::2? As opposed to relying on
autoconf addresses.
