Hello,

yep, i'm using them, i needed to know the max and anyone experiencing

Those are int and nothing in the kernel code prevents them having MAX_INT-1 assigned as a value. However you have a rather serious networking problem anyway if you exceed the predefined gc* values.


Some more information (besides reading the related kernel code):

problems with very big arp's

Yes, the time spent in the GC to reach the equilibrium is rather high with a high number of stale cache entries. Once gc_tresh3 threshold kicks in you get an aggressive table flush concurrent with the new neighbour entries.


arpd is marked as depricated or so!?

No, not at all ;).

Best regards,
