Hi,

  These are my environment.I have three routers.

    router A----------------------router
B-------------------------router C

   Router A connected router B through the interface ethernet0.Router B
connected router C through the serial0.
 router A#show config
               !
               ip multicast-routing
              !
              int e0
              ip pim den
             ip igmp join-group 224.2.2.1
             !
 router B#show config
               !
               ip multicast-routing
               !
               int e0
               ip pim den
               !
                int s0
               ip pim den
               !
 router C#show config
                !
                ip multicast-routing
                !
                int s0
                ip pim den
                !
 In router A and B,I can see the multicast route (*,224.2.2.1).In router
C,I don't see the multicast route (*,224.2.2.1),But I can ping the ip
address 224.2.2.1.WHY?What's wrong with this?

Any help will be appreciated.
