[zeromq-dev] EPGM packets

[Matteo Fortini]

Hi,
we just switched our PUB/SUB architecture on 0MQ from TCP to EPGM to 
reduce traffic and get over the need for a central repeater to have 
multiple publisher/multiple subscribers.
I tcpdump'ed the traffic to see what was going on, but I can only see 
repeated multicast messages from the publisher, but nothing from the 
subscribers. Is that normal? Is that because of UDP encapsulation?

Thank you in advance,
Matteo
