where did you pick the prefix? it looks to be a typo for
"fec0::2". Don't forget "prefixlen 64 alias" at the tail.
IPv6 prefix length is always 64, and we have multiple addresses on
an interface, which is "alias" in traditional ifconfig(8)'s mind.
also, take a look at /etc/netstart (or /etc/rc.d/network) - for
scope boundary's sake we install reject route for fec0::/10,
you need to comment that line out.

can you talk a little bit more about *how* it have failed? what
have you observed? did you check the packet trace via tcpdump?
how is your routing table configured? there are so many information
necessary to track your issue down.
