Thanks for your rapid response, Filip.

Here's the configuration of the interface:

UP,BROADCAST,RUNNING,MULTICAST,IPv4,NOFAILOVER>

And an example of traffic I see:

squirrel:/usr/local/tomcat5# snoop -r multicast 239.255.10.10
Using device /dev/ce (promiscuous mode)
128.117.224.86 -> 239.255.10.10 UDP D=2525 S=2525 LEN=49
128.117.224.85 -> 239.255.10.10 UDP D=2525 S=2525 LEN=49
128.117.224.86 -> 239.255.10.10 UDP D=2525 S=2525 LEN=49
128.117.224.85 -> 239.255.10.10 UDP D=2525 S=2525 LEN=49

So, it looks like both nodes are sending multicast pings.  Doesn't this 
mean it is enabled?  Thanks for your help!
