Use this page to define the multicast settings for JMS topics that are based on this template. Multicasting enables the delivery of messages to a select group of hosts that subsequently forward the messages to subscribers.
IP multicast is a simple broadcast technology that enables multiple
applications to "subscribe" to a given IP address and port number and
listen for messages. A multicast address is an IP address in the range
from 224.0.0.0
to 239.255.255.255
.

Multicast Address |
The IP address that this topic uses to transmit messages to multicast consumers. MBean Attribute
(Does not apply to application modules): Changes take effect after you redeploy the module or restart the server. |
Multicast TTL |
The number of routers that a message can traverse enroute to the consumers. A value of 1 limits the message to one subnet (which prevents it from traversing any routers). This value is independent of the JMSExpirationTime value. MBean Attribute
