[Pacemaker] need info multicast-corosync

[Winkler Norbert]

Hello again
At first sorry for this simple  (stupid?) question in this special forum 
so please don't lough:
I am still learning a lot trying to configure a cluster.
I am unterstand the sense of multicastadress  but i have still problems 
to handle it.
My nodes are 192.168.1.21 and 192.168.1.22 on eth1 (drbd is 10.10.10.1 
and 10.10.10.2 with crosover cable on eth0)
so my bindnetadress is 192.168.1.0
the corosync mcastadr 226.94.1.1
Port 5405

So do i have to make an
route add 226.94.1.1  netmask  whic.hone.????.???? dev eth1

or is it enough to have  mcastaddr in the corosync.config

If someone would be so kind to answer this question.

Thank you
Norbert Winkler
