I'm happy to post here now. Although, I'm not sure everything is working
correctly yet. The routes are definitely setup via rip44d:
# ip route | grep ^44 | head
44.0.0.1 via 169.228.34.84 dev tun0 onlink window 840
44.2.0.1 via 191.183.136.1 dev tun0 onlink window 840
44.2.2.0/24 via 216.218.207.198 dev tun0 onlink window 840
44.2.7.0/30 via 98.208.73.100 dev tun0 onlink window 840
...
Here's what you need to do to get rip44d running:
curl -O https://raw.github.com/hessu/rip44d/master/rip44d
chmod u+x rip44d
configure
set system package repository wheezy components 'main contrib non-free'
set system package repository wheezy distribution wheezy
set system package repository wheezy url http://http.us.debian.org/debian
commit
save
sudo apt-get install libio-socket-multicast-perl
sudo ./rip44d -i tun0 -p <the password>
** Definitely do not run apt-get upgrade - warned on the Ubiquti Wiki **
I still do not have my routing working properly though. I am unable to
ping any anything in 44/8. Still trying to figure this out, but having
fun in the process. It is probably something obvious, although they are
definitely going out the right interface.
$ ping 44.0.0.1

Hopefully the above to get rip44d will be of some use to someone anyway.
Thanks,
