Hi,

Can any one please help me increase the arp stale time of an ipv6 interface on linux platform ?

I have tried increasing the variable gc_stale_time but that doesnt work.

Thanks

(for more information see man 7 arp)

You want to set base_reachable_time higher, it defaults to 30 seconds. At 30 seconds entries can become stale at a range of 15 seconds to 45 seconds. If there is positive feedback the time increases.
