Re: [opendds-main] RTPS multicast binding

[Kohler, M. <Mik...@sa...>]

Adam -

 

Thanks for the quick reply and update.  It looks like it correctly
listens on the specified multicast interface, however, it's still not
sending the participant portion RTPS discovery over that multicast
interface.  So the handshake seems to fail.

 

I revised my configuration as follows:

[rtps_discovery/mydisc]

ResendPeriod=5

SedpMulticast=1

MulticastInterface=em4

 

[transport/myrtps]

local_address=10.99.101.5:0

transport_type=rtps_udp

multicast_interface=em4

 

And see the following debug output:

Is there a configuration piece I missed?

 

Thanks

Hi Mike,

	Using OpenDDS 3.4.1 and I have multiple network interfaces on
the system.  I would like to be able to specify which network interface
is used for the RTPS discovery (which interface the multicast group is
bound to).  Is this possible?


The subversion trunk version now has configuration options for setting
the network interface used for multicast with RTPS.  This was previously
only available in the "multicast" transport.  Please see the ChangeLog
for details on using the new options.
