Description
Resolution:
Set the option pgm_interface_addr in the mcast.cm file to control which NIC is used for receiving multicast messages.
setopt pgm_interface_addr <ip address of preferred NIC>
When the RTclient joins a group it will expect multicast messages to arrive on the declared NIC.
NOTE: RTclients never publish via multicast rather the RTclient establishes a TCP connection to RTserver
to which it publishes messages via unicast. RTserver may then pass the message to RTgms for multicasting
outbound RTclient messages, or may route via unicast to other RTservers. RTserver may also send messages to
subscribing RTclients via unicast if there are not enough RTclients to meet the group_threshold setting of
RTgms. Set the server_names option in RTclient to designate which IP is used for the connection between
RTclient and the RTserver.
