[Pacemaker] CMAN with multiple networks for HA communication

Dear List,

According to CMAN identify each node in cluster by hostname.
So I configure the IP address in /etc/hosts file as below.

...    node00.example.com    node01.example.com

So the corosync member show as below

[root at node00 ~]# corosync-objctl | grep member
runtime.totem.pg.mrp.srp.members.2.ip=r(0) ip(
runtime.totem.pg.mrp.srp.members.1.ip=r(0) ip(

My question is, is it possible to add more than one network for the HA
communicate between these nodes?
e.g. if is down. And another network, which be main
access network, still be up. the HA will use UP network to talk
instead of the down one.

Thank you in advance.
