Hi all- Does anyone do IPv6 multicast routing on FreeBSD? If so, what software do yo= u use? Any caveats or other things to be aware of? The only options I have seen are all in net/mcast-tools and I'm having some t= rouble with each of them. I do have "options MROUTING" in my kernel and IPv6= forwarding enabled on each host. I've had the best luck with "mfc": I can get packets to traverse a single ro= uter. However I can't get them to traverse a second one in either direction (= though that may or may not be a problem with mfc itself). The big downer of c= ourse is that each unicast source and multicast destination has to be explic= itly spelled out in each direction in the config file. Not at all scalable a= nd not compatible with the auto-configuration goals of my project. The one I think I'd like to use is pim6sd. However I have had no luck with e= ither it or pim6dd. Both will run but not pass packets, and they each compla= in that they cannot assign the requested ff02::2 address on either interface= . Any advice or suggestions appreciated. JN=
