ARP messages


i'm having the following issue, i have two machines using heartbeat and an ip phone to communicate with the servers (the servers run a sip application for voip); when heartbeat migrates the virtual ip to the other server the phone keeps sending the packages to the first server and NOT to the server with the virtual ip; i guess i should issue some command to broadcast the actual state of the arp...

Is there any way to do this?

Best Regards!

try running
arping -b <ip_address>
on another machine and then failover the master to slave and see if the mac address changes. If it doesn't there is something wrong with your hearbeat setup.

Thanks for the help,

But seems it did not work, i did the arping -b VIRTUAL_IP on the server that just got this virtual ip and al the requests from the phone were going to the other first server (that hasn't the virtual ip configured...) the heartbeat is not issuing any kind of arp messaging, i've seen some configurations of heartbeat were it makes the arp messaging by itself, but my heartbeat configuration is not doing this, am i missing something?
