https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202484 --- Comment #1 from olivier@cochard.me --- errno(2) translate error number 45 by a EOPNOTSUPP. And code in netinet/ip_mroute.c can return EOPNOTSUPP in 2 cases: if ((vifcp->vifc_flags & VIFF_TUNNEL) != 0) { CTR1(KTR_IPMF, "%s: tunnels are no longer supported", __func__); VIF_UNLOCK(); return EOPNOTSUPP; or } else { /* Make sure the interface supports multicast */ if ((ifp->if_flags & IFF_MULTICAST) == 0) { VIF_UNLOCK(); return EOPNOTSUPP; But a vtnet interface seems to correctly set IFF_MULTICAST because dev/virtio/network/if_vtnet.c includes: vtnet_setup_interface(struct vtnet_softc *sc) { ... ifp->if_flags = IFF_BROADCAST | IFF_SIMPLEX | IFF_MULTICAST; ... } Then how to troubleshoot deeper this problem ? -- You are receiving this mail because: You are the assignee for the bug.
