It's hard to understand what PIM is, or is not, doing without seeing full configuration files and show commands for both routers. You have only listed partial commands, which will not fully disclose your PIM configurations. There are several little gotchas in working with Protocol Independent Multicast (PIM) on Cisco routers. One of the first questions I would ask is what kind of RP have you established, or are you using auto- rp (the preferred method IMHO). The next thing I would probably check is what does the multicast routing table look like once you have enabled PIM? Do a "show ip mroute" to see what is happening. While just guessing due to lack of a complete picture, it is possible that PIM has been broken due to a lack on an RP. If that is the case, it might affect other multicast enabled protocols, such as OSPF and HSRP.
If you just wish to get multiucast up and running, try dense mode first. Once that is running properly, then try to get sparse mode up and running. I would focus my energies on using Auto-RP, which I have found much more reliable and easier to troubleshoot than static RPs. It also tends to be more scalable. Finally, you may want to take a peek at this article and focus on the PIM/HSRP interactions. It may or may not apply to your situation(watch wrap): http://www.cisco.com/warp/public/619/hsrpmcast.html Try this link for configurations of static and auto-rp's: http://www.cisco.com/warp/public/cc/pd/iosw/tech/rppim_rg.htm Here's also a good page to checkout: http://www.cisco.com/warp/public/105/48.html Note Cisco's recommendation on the first paragraph under Dense Mode: "Dense Mode Cisco recommends using Protocol Independent Multicast (PIM) sparse mode, particularly Auto-RP, wherever possible, especially for new deployments. " The advice listed above comes directly from Beau Williamson himself. If you want a good book on multicasting and PIM, you need to read Beau Williamson's book.
