Hi,I'm using smcroute to join and leave multicast groups and I don't understand the behavior of FreeBSD when the group is left. Here is what I do: smcroute join em1 10.3.4.5 224.0.55.55 ifmcstat -i em1 em1: inet 10.10.0.1 igmpv3 rv 2 qi 125 qri 10 uri 3 group 224.0.55.55 mode include mcast-macaddr 01:00:5e:00:37:37 group 224.0.0.1 mode exclude mcast-macaddr 01:00:5e:00:00:01 smcroute leave em1 10.3.4.5 224.0.55.55 ifmcstat -i em1 em1: inet 10.10.0.1 igmpv3 rv 2 qi 125 qri 10 uri 3 group 224.0.55.55 mode undefined mcast-macaddr 01:00:5e:00:37:37 group 224.0.0.1 mode exclude mcast-macaddr 01:00:5e:00:00:01 At this point, I expected to have no membership left on em1 for 224.0.55.55 but ifmcstat shows that the interface is still a member of the group but in undefined mode. I was wondering if anybody could tell me why the group membership seems to be transitioned to a (*, G) membership when all the (S, G) memberships are removed.
