Did you run mergemaster after you upgraded? How old/what version of
FreeBSD did you upgrade from?

Can you please paste the exact error message?

This is no longer needed.

It's likely that you need to add inet6 before fe80 there:
ifconfig_bridge0_ipv6="inet6 fe80::2%bridge0 prefixlen 64"

See the rc.conf man page on this one, this should probably be:
ifconfig_bridge0_alias0="inet6 2001:abcd:abcd:abcd::x prefixlen 64"

If the above doesn't fix your problems, what ifconfig command line(s)
work for you?
