I've never connected up routers through a 2950 (which is what the OP is using - right?), but it looks like igmp snooping on a 2950 does learn the ports going to PIM routers: c2950>sh ip igmp snoop [.. snip ..] Vlan 1: IGMP snooping : Enabled Immediate leave : Disabled Multicast router learning mode : pim-dvmrp Source only learning age timer : 10 Last member query interval : 1000 CGMP interoperability mode : IGMP_ONLY Lee ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

Re: [c-nsp] Need help with setting up ip multicast routing...correction
You will need to have PIM enabled on all of the interfaces between the source and receiver, and all of those devices need to have an RP (and they should be the same: easiest solution is statically enter this on all of them). Also, make sure that PIM is enabled on the 8840's interface that matches the RP-address. There's a lot more to optimization and troubleshooting, but that should provide initial connectivity.

Re: [c-nsp] Need help with setting up ip multicast routing...correction
I have a few questions: 1. Can the servers ping the encoders? 2. Are the encoders connected at layer three and running PIM, or are they layer two? 3. Is this source-specific multicast? If so, you need to be running IGMP v3 on your layer two interfaces. -John On Fri, Oct 8, 2010 at 1:46 PM, Steven Pfister wrote: > The line below reading "non-multicast traffic" should be "non-multicast > traffic seems to be OK between the vlans" > > Thanks! > > Steve Pfister > Technical Coordinator, > The Office of Information Technology > Dayton Public Schools > 115 S.

Re: [c-nsp] Need help with setting up ip multicast routing...correction
The line below reading "non-multicast traffic" should be "non-multicast traffic seems to be OK between the vlans" Thanks!

Ludlow St. Dayton, OH 45402 Office (937) 542-3149 Cell (937) 673-6779 Direct Connect: 137*131747*8 Email spfis...@dps.k12.oh.us >>> "Steven Pfister" 10/8/2010 3:39 PM >>> We've got a client who needs to set up multicast routing between two sites (and between two vlans) in order for some video encoders at remote sites to find servers at the central site. I've never had experience with this. The setup looks something like: encoders -> Cisco 4506 -> (CSME) -> Cisco 4510 -> Cisco 8540 -> Cisco 3560 -> servers The Cisco 4506 is the default gateway for the remote site vlan, let's call it vlan 22. The Cisco 4510 is the default gateway for the central site vlan, let's call it vlan 33 Also factoring into this, a previous (before my time here) set up of ip multicasting in sparse mode was done using other remote sites using 3640 routers with the 8540 as the RP. I don't know what it was intended for, or if it was ever successfully configured, but I'm not sure it's in use any more. Here's what's been done so far... the Cisco 4506 now has: ip multicast-routing ip pim rp-address 10.99.99.1 [the address of the 8540] interface Vlan22 ip pim sparse-dense-mode [the video encoder vendor recomended this] [there's also a ip helper-address pointing to a local server for dhcp] The 4510 has: ip multicast-routing ip pim rp-address 10.99.99.1 interface Vlan33 ip pim sparse-dense-mode Observations: - non-multicast traffic - the encoders never see the servers - "show ip pim neighbor" shows no results (just headers) - "show ip multi int vlan33" on the central site shows a large and growing number of multicast in packets, but zero out packets. Same results for vlan22 on the remote site. Could the problem be igmp packets not getting exchanged? Like I said, I've never set up ip multicast routing before. Thanks!
