OK, the above indicates that the FEA has received and forwarded the
UDP packet to the RIPng module.

After you started using the link-local addresses in your
configuration what is the output of "show ripng peer statistics all"
xorpsh command? It should show something like:

user at hostname> show ripng peer statistics all 

* RIP statistics for peer fe80::xxxx:xxxx on rl0 rl0 fe80::yyyy:yyyy

There was one problem in your config file. Inside the policy
statement you need to replace

                network6: ::/0

with

                network6 <= ::/0

This could explain why the connected routes weren't exported.

P.S. For reference purpose this is my config file. Obviously, you
need to replace the link-local address inside the ripng block with
your own link-local address.
