heartbeat

Hi all I would ask anyone what is the best layer 2 medium for heartbeat in Linux and how it's best configured.

More precisely I've been thinking about a dedicated NIC for that purpose but then i thought that if a switch breaks then i would loose the heartbeat connection for most of the cluster and STONITH 'BUM'!!! Will probably loose my job after :)

Distributing the heartbeat onto the main NICs of every node trough a vif sounds reasonable but im not sure if this is the best option (at least the switches are redundant to some extent).

Is it possible to use heartbeat over a bonded interface and that sounds reasonable? Do you have any other tip/solution for that issue?
