[ClusterLabs] IPaddr2, interval between unsolicited ARP packets

[Shinjiro Hamaguchi]

Hello everyone!!


I'm using IPaddr2 for VIP.

In the IPaddr2 document, it say interval between unsolicited ARP packets is
default 200msec and can change it using option "-i", but when i check with
tcpdump, it looks like sending arp every 1000msec fixed.

Does someone have any idea ?

Thank you in advance.
