[CentOS] Two sets of Heartbeat HTTPD clusters on same subnet

Hi all,

I am new to Hearbeat so please be kind :) I also posted this on
Linux-HA lists with no responses so I posted it here.

I have successfully configure two machines to use heartbeat to cluster
httpd. The two nodes are called etk-1 and etk-2. I am trying to
configure another two machines to act as a separate cluster (on the
same IP subnet). These two nodes are called radu-1 and radu-2.

Obviously being a broadcast protocol radu-1 and radu-2 get these
messages from etk-1 and I can't seem to get radu-1 and radu-2 to
cluster (mostly probably because they are not getting the messages
from the right nodes).

Should I just change the name of the test, if I do that I get heaps of
WARNING log messages.

Is it possible to have two sets of clusters in the one IP subnet?

If yes what do I have to change so these clusters don't send messages
to the wrong nodes.
