dear all I'm using vlc for ipv6 multicast on the ipv6 in ipv6 tunneling. but there are some problems. my test environments; pc router: freebsd 4.10R host: linux (kernel 2.6.11), windows xp service pack2 pim6sd: kame-20050131-snap-kit vlc: vlc-0.8.2 and vlc-0.7.2 dbeacon: dbeacon-0.3.5 network topology H1 --- R1(rp, bsr) --- ipv6 in ipv6 tunneling --- R2 --- H2 * H: host, R: pc router I tested vlc; ver 0.8.2 and 0.7.2, and dbeacon dbeacon was no problem. but vlc test was shown strange results. I success vlc test when h2 is a sender and h1 is a receiver. but the opposite case (h1-sender, h2-receiver) was failed tcpdump result at the h2 is like this when h1 is a sender and h2 is a receiver. --> 02:48:08.488389 fe80::204:75ff:fee2:21e5 > ff0e::8320:2078: HBH icmp6: multicast listener report max resp delay: 0 addr: ff0e::8320:2078 [hlim 1] I checked pim6sd log of sender(h1) and I can see following message --> 19:57:29.920 warning - SIOCGETSGCNT_IN6 on (2001:220:806:11::17 ff0e::8320:15): No such process 19:57:29.920 Deleting MFC entry for source 2001:220:806:11::17 and group ff0e::8320:15 19:57:29.920 warning - setsockopt MRT6_DEL_MFC: Can't assign requested address 19:57:29.920 Join_or_prune : upstream_router is null 19:57:29.920 src_action = 0 19:57:29.920 SSM src_action = 1 I cann't understand why one direction (from h2 to h1) works but the other direction(from h1 to h2) does not work in addition to no problem with dbeacon. thanks.. -- followings are pim6sd logs related with multicast pim6sd log of H1 --> 19:57:13.113 Cache miss, src 2001:220:806:11::17, dst ff0e::8320:15, iif 6 19:57:13.114 create group entry, group ff0e::8320:15 19:57:13.114 Rp_grp_match found 3ffe:2e01:1:e::1 for group ff0e::8320:15 19:57:13.114 create source entry, source 2001:220:806:11::17 19:57:13.114 create SG entry, source 2001:220:806:11::17, group ff0e::8320:15 .. 19:57:15.910 Cache miss, src 2001:220:806:11::17, dst ff0e::8320:15, iif 6 19:57:15.910 create group entry, group ff0e::8320:15 19:57:15.910 Rp_grp_match found 3ffe:2e01:1:e::1 for group ff0e::8320:15 19:57:15.910 create source entry, source 2001:220:806:11::17 19:57:15.910 create SG entry, source 2001:220:806:11::17, group ff0e::8320:15 .. 19:57:29.920 warning - SIOCGETSGCNT_IN6 on (2001:220:806:11::17 ff0e::8320:15): No such process 19:57:29.920 Deleting MFC entry for source 2001:220:806:11::17 and group ff0e::8320:15 19:57:29.920 warning - setsockopt MRT6_DEL_MFC: Can't assign requested address 19:57:29.920 Join_or_prune : upstream_router is null 19:57:29.920 src_action = 0 19:57:29.920 SSM src_action = 1 .. 20:01:12.929 Receiving PIM v2 Join/Prune from fe80::200:f0ff:fe94:5be 20:01:12.929 I'm the target of the JOIN/PRUNE message 20:01:12.929 Number of groups to process : 2 20:01:12.929 Group to process : ff0e::8320:15 20:01:12.929 Number of join : 1 20:01:12.929 Number of prune : 0 20:01:12.930 I'm looking for the (*,*,RP) entry, skip to next entry 20:01:12.930 Group to process : ff0e::1234:1234 20:01:12.930 Number of join : 1 20:01:12.930 Number of prune : 0 20:01:12.930 I'm looking for the (*,*,RP) entry, skip to next entry 20:01:12.930 Group to process : ff0e::8320:15 20:01:12.930 Number of join : 1 20:01:12.930 Number of prune : 0 20:01:12.930 Rp_grp_match found 3ffe:2e01:1:e::1 for group ff0e::8320:15 20:01:12.930 The rp for this JOIN/PRUNE is 3ffe:2e01:1:e::1 20:01:12.930 Group to process : ff0e::1234:1234 20:01:12.930 Number of join : 1 20:01:12.930 Number of prune : 0 pim6sd log of H2 --> 20:13:12.062 accepting multicast listener report: src fe80::204:75ff:fee2:21e5,dst ff0e::8320:15, grp f f0e::8320:15 20:13:12.062 The group doesn't exist, trying to add it 20:13:12.062 creates a group in MLDv1 compat-mode for ff0e::8320:15 on Mif em0 20:13:12.062 create group entry, group ff0e::8320:15 20:13:12.062 Rp_grp_match found 3ffe:2e01:1:e::1 for group ff0e::8320:15 20:13:12.062 Adding vif 1 for group ff0e::8320:15 .. 20:13:36.097 accepting multicast listener report: src fe80::204:75ff:fee2:21e5,dst ff0e::8320:15, grp f f0e::8320:15 20:13:36.097 The group already exists 20:13:36.097 goes into MLDv1-compat-mode for ff0e::8320:15 on Mif em0 20:13:36.098 Adding vif 1 for group ff0e::8320:15
