Basically all stations that are going to participate, you add routes in the configuration file that point the daemons to the same multicast group. As the ax25ipd daemon starts up, it will see the 224.0.0.0/4 address and join that group. I haven't looked into IPv6 multicast at this stage: IPv6 support in general is needed in ax25ipd. > In the IP world, we have IGMP to support join/leaves and > pragmatic general multicast (PGM) to support selective re-transmits for > reliable transport.

Any plans to submit your patch to the upstream repositories like: > > AX.25 repo: http://www.linux-ax25.org/wiki/CVS VE7FET's more > current repo: http://code.google.com/p/linuxax25/ Well, I CCed Ralf in my patch email, I'm guessing he maintains the git repository for the ax25-apps project. I didn't know of the latter's existence. Regards, Stuart Longland
