Hi, I have problem with multicast routing on my network. I tried mrouted and also pimd, but always same problem. When I set mrouted or pimd on one router, everything works fine, but when I start mrouted/pimd on another one, routing die. In moment when I start anorher mrouted/pimd /proc/net/ip_mr_cache is cleaned. My topology: gateway (no mrou...

Hello list, Not sure if I am asking the question in the correct list. I am a newbie trying to get multicast routing to work on my linux 2.4 kernel. I am using usc pimd code. I have pimd which sets up the route in the kernel [ /tmp]# ip mroute show (22.22.22.1, 224.0.1.20) Iif: eth2 Oifs: eth1 [ /tmp]# I can see data packets arriving on eth2 [/tmp]# tethereal -i eth2 Capturing on eth2 0.000000 22.22.22.1 -> 224.0.1.20 UDP Source port: 327...

.../4 and for a specific multicast group (say 239.16.2.2) to the netB and netC "devices", but the multicast traffic isn''t getting out of its source LAN. Are there ip commands that will do it? Do I need additional software running for multicast? I couldn''t get mrouted or pimd to compile on Fedora Core 4. I installed xorp but haven''t tried running it yet because I''m very confused about what is needed, besides the basic kernel and iproute2, for a multicast-capable Linux router. Thanks.

I have a standard 3 interface shorewall setup and I want to receive multicast stuff from ''net'' -> ''loc''. This requires me, first, to do an IGMP join which involves 192.168.1.x -> 224.0.0.x being NATed out as the ''net'' interface''s IP address. Obviously replies have to be NATed back to ''loc'' addresses. Can

...'. If I configure the internal ifc in mrouted to ''passive'', IGMP membership reports are forwarded. However, the source address is the private address 192.168.1.1 on the internal interface so at least not my IP becomess member of the multicast group. I plan to try zebra or any pimd related multicast routing sw. I would prefer not to run a daemon for static routing, but as I understand it, this is not possible the way multicast works: There has to be dynamic routing. It is not possible to bridge just multicast and route unicast. Of course, the multicast dynamic routing could...

How do the Multicast routers sniff IGMP/MLD messages from the network? I checked the XORP, pimd etc. Most of them just open a RAW socket with protocol set to IPPROTO_IGMP. But using this the router gets the packets addressed to 224.0.0.1 only. How does it receive IGMPv2 and IGMPv3 membership reports sent by other hosts? Thanks, Sachin

...client''s multicasting abilities would be a bonus. I see that rendezvous sends out packets with a TTL of 1 and expects them back with a TTL of 255 so I guess I will have to do some packet mangling in iptables. The limited documentation out there recommends running a multicast router like PimD. What does this add to the setup? Surely it''s just a cast of some iptables rules allowing 224/4 between networks? Am I missing the point here? Any good documents on multicast? S. -- Simon Tennant ________________ http://imaginator.com/~simon/contact

Hi, I have seen http://www.tinc-vpn.org/pipermail/tinc-devel/2010-October/000473.html and so tried out for myself to see if multicast would work in tinc using routing mode. I'm using tinc 1.0.19. My test involved sending a ping out on 224.1.1.1 (as 224.0.0.0/24 is a special case), and while I could see the traffic reaching the other tinc daemons, it never seemed to go out to the local

I''m just looking for a quick sanity check to make sure what I''m finding is really all necessary here. I''m upgrading a gateway/firewall from Linux 2.4 to 2.6 using Mandrake 10.1. In the old 2.4 kernel I structured my firewall rules around the ipsec0 interface, which I understand isn''t present with Openswan running under 2.6 (no KLIPS). Ok, So as I start to
