Comment 0 for bug 1409548

When deploying a hacluster, the multicast address defaults to a fixed address of 226.94.1.1.

This means having two haclusters on the same network segment will cause no end of conflicts and other unexpected behaviour.

The recommended address range (to simplify) for private address space is 239.[192-255].[1-254].[1-254] (ref rfc2365, and specifically note the exclusion of all 1s and all 0s)

When a hacluster is deployed without a mulitcast address it should be randomly allocated from that pool.
