Thanks for the hint, didn't now that something like this exists. Following up on my earlier mail, I wasn't able to reproduce the issue with more recent kernel versions. (tried 4.7) So I guess someone must have fixed it somewhere between 3.16 and 4.7. :) Okay, will check the git and probably try to backport it. Again, sorry that I did not check immediately with the more recent kernel versions. Wasn't expecting that much has changed in this area. But my request for information with regard to the FIB data structure still remains, since I'm curious about how it actually works. (And I already spent some time trying to understand it.) Thanks for your help, everyone! Andreas
