Set the appropriate network for multicast traffic

When developing or testing multicast applications, after testing them locally, you might want to test them over a multicast enabled network. If the application only transmits locally, you might have to edit the MQClient.ini file as shown later in this section. If the machine setup is using multiple network adapters, or a virtual private network (VPN) for example, the Interface parameter in the MQClient.ini file must be set to the address of the network adapter we want to use.

If the Multicast stanza exists in the MQClient.ini file, edit the Interface parameter as shown in the following example: Change:

Multicast:
Interface       = 127.0.0.1

To:

Multicast:
Interface       = IPAddress

where IPAddress is the IP address of the interface on which multicast traffic flows. If there is no Multicast stanza in the MQClient.ini file, add the following example:

Multicast:
Interface       = IPAddress

where IPAddress is the IP address of the interface on which multicast traffic flows.

The multicast applications now run over the multicast network.
