Hello,

Some news about this... If I change vhid on the backup node this problem
doesn't occurs since the ARP for the master node is still in cache and
backup node now has a different mac address for the carp interfaces. Of
course changing vhid and IP doesn't give any trouble at all.
It seems the backup node is messing with arp (maybe at switch level ???)
when it's coming back!
All switches are CISCO 2900 and 3500. Is there any recommend configuration
for these switches ?

Thanks,
John
