There has been a significant change between FreeBSD 4.3 and 4.4.
FreeBSD 4.4 now rejects a prefix length less than 128 when a
destination address of a p2p link is specified. So, please configure
the gif as follows:
# ifconfig gif0 inet6 3ffe:xxx:x:x::1e 3ffe:xxx:x:x::1d prefixlen 128 alias
or
# ifconfig gif0 inet6 3ffe:xxx:x:x::1e prefixlen 126 alias
("126" can actually be an arbitrary value less than 128)
