Hi, did anyone find a solution or workaround regarding this issue? Considering a router use case. I have looked at rt6_stats, total route count is around 78k (full view), and around 4100 entries in the cache at the moment on my first router (forwarding a few Mb/s) and around 2500 entries on my second router (forwarding less than 1 Mb/s). I have reread the entire thread. At first, Alarig's research seemed to lead to a neighbor management problem, my understanding is that route cache is something else entirely - or is it related somehow?

We agree then, and I act as a router on all those machines.

This is the result of PMTUd. But when you are a router, you don't need to do that, so it's mostly a problem for end hosts.

The information needs to be stored somewhere.
Why has it to be stored? It’s not really my problem if someone else has a non-stantard MTU and can’t do TCP-MSS or PMTUd.
