[Babel-users] scaling of babeld

[Christof Schulze]

There are a few Freifunk communities in Germany running babeld allowing 
roaming in ipv6 only using host routes. We have been able to break it 
(100%CPU on nodes) with a very old version while we had 1000 clients. 
After the fix was implemented we have not been able to break it since.



Cheers
Christof
