Can you describe your traffic forwarding setup in more detail?
Is it only pf, or do you run netgraph, or other things as well?
Do you use flow routing?

How frequent does this happen?

I'm trying to create a stack graph to see which parts of the network
stack are involved in handling your packet.


Hi,
In my case, I do use PF for filtering and NAT (without routing options like 'route-to' or 'reply-to') together with ALTQ (PRIQ).
I also use IPFW+Dummynet combo for shaping.

net.inet.ip.sourceroute: 0
net.inet.ip.accept_sourceroute: 0

Router traffic is about 300Mb/s in peak.

Frequency:

I do only monitor default route change, but this bug also affects static routes (i.e. I have one static route and it changes more frequently that default route).

Please let me know if I can provide any more feedback.
