Newell" To: questions@FreeBSD.org Subject: Multicast in V2.0R Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: questions-owner@FreeBSD.org Precedence: bulk I'm trying to get the multicast stuff working in V2.0R and am having some problems. I want to run mrouted on the same machine as I'm running the various tools (e.g. vat, nv, etc.) According to the FAQ to bring up multicast support you need to build a kernel with options MROUTING options MULTICAST options LKM then load the file "ip_mroute_mod". I built the kernel, and mrouted does indeed run. When I try to load the "ip_mroute_mod.o" module using the command modload /lkm/ip_mroute_mod.o I get billions of error messages, and modstat reports nothing loaded (I suspect I'm not doing this right, but there are no instructions for how to do it, so...) No matter what I do I can't get anything to show up in sd, and vat does not function. When I fire up mrouted I *DO* see traffic over the link, and "mrouted -d" yields: debug level 2 mrouted version 3.3 installing ed0 (198.116.75.11 on subnet 198.116.75) as vif #0 - rate=0 installing tunnel from 198.116.75.11 to 198.116.2.105 as vif #1 - rate=2 pruning on Virtual Interface Table Vif Name Local-Address M Thr Rate Flags 0 ed0 198.116.75.11 subnet: 198.116.75 1 1 0 querier pkts in : 0 pkts out: 0 1 ed0 198.116.75.11 tunnel: 198.116.2.105 1 32 2 pkts in : 0 pkts out: 0 Multicast Routing Table (1 entry) Origin-Subnet From-Gateway Metric In-Vif Out-Vifs 198.116.75 1 0 1* update 137 starting at 0 of 513 but I, as I said, sd/vat don't function.
