11.2.0.2 clusterware haip - different ip - different switch

two nodes cluster.
I got strange behaviour on oracle clusterware 11.2.0.2 I had configured 2 nic (10gbit):
node1-priv1 192.168.128.x
node1-priv2 192.168.129.x

node2-priv1 192.168.128.y
node2-priv2 192.168.129.y

every NIC is plugged on the different switches.

the problem is when one node (let say node 1) restart (manual crs restart, machine restart),
th node cannot join the cluster again, this message appear:

....

[ CSSD][48]clssnmvDHBValidateNCopy: node 2, node2 2, has a disk HB, but no network HB, DHB has rcfg 189043337, wrtcnt, 24357941, ATS 726816912, lastSeqNo 24357908, uniqueness 1293699385, timestamp 1298437269/
....

repeating
..... repeating

from each node, I can ping
but (may be) multicast problem.

patch 9974223 has been applied, hence multicast use 224.0.0.251.

so, now I have to stop crs on node1, stop crs on node2. then startup crs on both node will then fine.

is the different of network segment causing problem?

thanks for share
