I use Ubuntu so I can't say 100% but I would expect so... I use it successfully in my cluster so I know it *can* work in general.

Your cidr_netmask looks odd to me given the broadcast address... should it be 24 or 23 not 22?

Don't need any of these parameters really... just clone cl_vip ip_vip and nothing else. global-unique could be part of the problem too

interleave is default false if not defined and pretty sure you want it false
globally-unique is default false and should not be true for your use case
clone-max defaults to the number of nodes in cluster so if you have 2 nodes you get 2 clones
clone-node-max defaults to 1
target-role and is-managed are auto-generated when you did certain cluster actions and are fine as is or removed

should not be (unique) as I stated above

I would try the changes above to the clone and (possibly) the netmasks.

Then if it's still not pingable I would stop any firewall on the servers temporarily and test just to rule the firewall out.

If that doesn't work how about output from "crm_mon -fr1" "crm configure show". And "ip a s" from each node
