This specifies the UDP port number. It is possible to use the same multicast
|
|
|
address on a network with the corosync services configured for different
|
|
|
UDP ports.
|
|
|
+Please note corosync uses two UDP ports mcastport (for mcast receives) and
|
|
|
+mcastport - 1 (for mcast sends).
|
|
|
+If you have multiple clusters on the same network using the same mcastaddr
|
|
|
+please configure the mcastports with a gap.
