Subject RE: network of brokers
Date Wed, 17 Jan 2007 20:19:00 GMT
More info:  I was also able to run iperf multicast tests
( successfully between
the hosts running the brokers.  I assume this means that multicast works
on my network, but I'm still not seeing any sign that the brokers are
connecting with each other.

I'm not sure how to know if multicast works or not.  If I ping, I get responses multiple "multicast peers".  Is that enough
to verify?  Is there some other way to verify multicasting?

I see no INFO messages in the broker consoles (>&file) indicating
connections with other brokers.

Does multicast work on your network?

When the brokers connect to each other you will see INFO messages on the
broker consoles saying that they have established connections to each
