[openib-general] Gratuitous ARP

[Jay Higley]

I am looking into building a high availability cluster using IPoIB for 
the backbone.  However, I would like to be able to use gratuitous ARP 
replies to switch IP to MAC address mappings to effect the failover.  
Will this work with the OpenIB stack?  What about if the hosts in 
question are using multicast to communicate?  Will the switchover also 
support the addition of the new host into the correct multicast groups?
