I worked on a network with the following protocols : OSPF, IGMP, PIM sparse dense mode, Anycast RP and MSDP. Topology is made of rings with four RP. On each sites we've got an MRV box to convert FastEthernet to FO. Or it appears that when we disconnected the FO on the MRV, some sites disappears from the RP ( sh ip msdp sa-cache). Have you any ideas ?
Thinks. Indeed OSPF converged, we checked using traceroute before breaking the link and after, so it's ok for unicast. But people on the impacted site didn't receive multicast flows. I join a schema and configs of site site B and one RP. We break the FO on site D and we've got impact at the opposite of the network in site B for example. Thanks for your help.
Thanks for your help, i put back the attachments. In fact people on both sites are sources and receivers in the same time (phonie). We've checked RPF on the neighbor router when this happens and effectively we've got RPF check failure :
