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!
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_ospf/configuration/15-e/iro-15-e-book/ip6-route-ospfv3.htmlI'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.
