I did some testing on this and Yasser is right on the money. Assign R1 to announce for the 236.1.1.0 and R2 to announce for the 236.1.8.0 networks. I can provide configs if you need, but there is not much to it. The basics for me was: Configure the interfaces between the routers and the clients for sparse-dense-mode and version 2 ( I don't know if V2 is needed ) Assign one of the routers as the RP mapping agent.
You can test the config in several ways. I used the mcaster application on a lan segment. Else use the ip igmp join-group command for several of the groups. If you have the doc cd, read this. Its great IMO. http://127.0.0.1:8080/cc/td/doc/product/software/ios122/122cgcr/fipr_c/ipcpt 3/1cfmulti.htm#xtocid38990 Thanks Larry -----Original Message----- From: YASSER ALY [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 17, 2002 7:55 PM To: [EMAIL PROTECTED] Subject: Re: Multicast quesion.. [7:53449] Hi Paul, To configure a router to be an Auto-RP use the following command: Router(config)# ip pim send-rp-announce scope This should be applied on both R1 & R2 in your scenario. To configure a router a RP mapping agent (R4 in your scenario) use: Router(config)#ip pim send-rp-discovery scope Routers configured as Auto-RP advertises Cisco-RP-Announce at 224.0.1.39 while routers configured as RP mapping agents listens on this IP and sends inturn the RP-to-group mappings in an auto-RP RP discovery message to the well known Cisco-RP-Discovery 224.0.1.40 PIM DRs listen to 224.0.1.40 to determine which RP to use. Kindly let us know if this will work out or not as I am not that strong with Multicast and it happens for me to be studying it now so I looked for the commands but never tried it myself.
