Hi Alex, I tried the mcastsend and mcastrecv on my two raspberry Pi's running 9front. I'm seeing similar routes as in my own experiment without the interface number, tagged as 4m for IPv4 multicast. I can ping each device from the other using their unicast addresses. Unfortunately, it doesn't seem to be working. Both ends are sitting idle. Do you remember if you needed to add/remove routes to make it work? Also, did you use 9front or the bell labs distribution? Thanks, Chris |
| Thank you Alex, I will give these a try tonight. I'm happy to hear that multicast can work and it's likely just some silly mistake on my end.
