Greetings, I'm quite stuck and am hoping I can find some guidance. I have N PIDs carrying MPE multicast packets that have been exposed via dvb0_N interfaces. It does not appear that multiple PIDs can be assigned to a single DVB network interface via V4L/DVB API.
My goal is to have all packets (in general, multicast or not) arrive on a single interface (i.e. sat0). That is, a tcpdump -i sat0 will show dvb0_1, dvb0_2, ... , dvb0_N packets. Statically routing (smcroute) does work but, the multicast group address isn't generally known or joined via this process. The other process is pre-existing software that knowns nothing of dvb0_N interfaces too. Bridging the dvb0_N interfaces doesn't show the multicast packets on the bridge interface (i.e. br0 via bridge-utils). I had thought this would be the solution. Routing all multicast packets via route/iptables didn't seem to work either. From what what I gather multicast packets can't be routed 'normally'. I have attempted some with a dynamic multicast router such as mrouted without success. Chance this is my limited experience in this domain, I don't fully grasp the necessities with IGMP and such. So, I think the question is, what would be the method you'd choose to combine packets received from dvb0_N interfaces into a single interface? Can this be done multicast agnostic? Without static routing?
