MulticastTest for Load balancing issue

Hi,

We are currently facing issues with Load balancing using IIS Proxy plug-in. 
[b]__WebLogicBridgeConfig list of dynamic servers does not return both
servers[/b]. MulticastTest is the first resolution suggested by Bea Support on
this page
http://support.bea.com/application_content/product_portlets/support_patterns/wls
/HTTPLoadBalancingInClusterUsingProxyPlug-inPattern.html

Can someone please interpret following results of second utils.MulticastTest
test. 

Thanx & Reagrds,

Sagar

I carried out two multicast tests with three machines with names ES01, ES02
& STAGE with different IP & Ports on the network. 

Following extract is from ES01 with IP [b]237.0.0.2[/b]  & port [b]8052[/b].
It finds 2 neighbors on lines 12 & 13 (ES02 & STAGE). Message exchange
also looks fine.

[pre]1	H:\>java utils.MulticastTest -n ES01 -a 237.0.0.2 -p 8052
2	***** WARNING ***** WARNING ***** WARNING *****
3	Do NOT use the same multicast address as a running WLS cluster.
4	
5	Starting test.  Hit any key to abort
6	
7	Using multicast address 237.0.0.2:8052
8	Will send messages under the name ES01 every 2 seconds
9	Will print warning every 600 seconds if no messages are received
10	
11	                I (ES01) sent message num 1
12	New Neighbor ES02 found on message number 1
13	New Neighbor STAGE found on message number 1
14	Received message 2 from ES01
15	                I (ES01) sent message num 2
16	Received message 2 from ES02
17	Received message 2 from STAGE
18	Received message 3 from ES01
19	                I (ES01) sent message num 3
20	Received message 3 from ES02
21	Received message 3 from STAGE
22	Received message 4 from ES01
23	                I (ES01) sent message num 4[/pre]

Following extract is also from ES01 with IP 237.0.0.1  & port 8050.
[b][u]Note that this IP & port is also used by Weblogic cluster.[/u][/b]  In
this case, test finds 3 neighbors on lines 12 & 16 (ES02 & STAGE) and
another on line 13 with name "úWÿ­º♀sr ‼weblogic.rj". 

I am not sure if cluster is responding here. On 2 physical machines, we have 3
services - admin, Server_1 & Server_2, shouldn't it find more
"Neighbors" if cluster is responding to test?  

Regarding Message exchange, there several "Duplicate messages"
received from this neighbour like on line 17 and 35.
