Hi Vlad,
I am using linux kernel 2.6.32 and wondering if the fix you are
referring is after that ?
I would like to know if MIB variable SCTP_MIB_OUTSCTPPACKS is picked
up by ICMP to figure out if neighbour is stale/unreachable/delay etc.
? Can you pls. point me to variable which is being set by SCTp on
successful packet out and pickup by ARP to figure out if resolution is
required or not ? I am sorry for writing personal mail but I am in
need of solution faster.
I just checked, and we don't appear to have this fix. Let me see if I
can cook something up for you to test.

Hello All,
I have one basic SCTP client and server ( having single network
connection) and client is continuously sending data to server every 1
second. I am seeing that server is sending ARP request every 20
seconds or so ( see below logs) for client IP address. If I use TCP
client/ server instead of SCTP, I see that ARP request is being sent
every 4 minute. Can somebody clarify why its happening or if my
observation is wrong ?
There was an old bug that SCTP didn't update the route forward progress
thus causing NUD to kick in even though reachability was configured
through SCTP. I thought it was fixed a long time ago. Which kernel
version are you using?
