Broadcast is not an option with corosync if you're using separate subnets for each node. For examples on how to configure corosync.conf please read https://github.com/corosync/corosync/blob/master/man/corosync.conf.5 as it has the most up-to-date information. You might have to concern yourself with the transport between the two geographical locations, as corosync is sensitive to network latency, and thus not recommended/viable for setups across WAN links. Maybe it works over FC or Infiniband, but it all depends on the transport atm.
