Hi, I am running the latest version of EMANE, from the repo, on an Ubuntu 11.10 host. My problem is that I can not receive multicast packets over the radio interface. Unicast works without issue. By default, there is a route setup by EMANE to 224.0.0.0/4 pointing to bmf0, the bridge interface. I am using multicast address 224.1.0.1, and when using the default setup I am receiving packets over bmf0 interface, which is not what I want; obviously I want to receive the packets over the emane0 radio interface. If I add a route to 224.1.0.0/24 to emane0, I can the see packets arrive on emane0 using tcpdump, but they are never received by my application. I found an older posting: http://pf.itd.nrl.navy.mil/pipermail/emane-users/2012-May/000339.html where they say I should set rp_filter to 0 in order for applications to receive multicast packets. I tried setting rp_filter to 0 on ALL interfaces, and that didn't help. I am still not receiving any packets.
Could someone help me find the issue? Thanks, Anders
