Chenyan,
Assuming you have set up dense-mode (source path), sparse-mode (manual
RP), or sparse-dense mode (auto-RP) on all the routers, you will want to
add igmp:
If you want routers to be multicast "receivers", you need to add "ip igmp
join-group 228.1.1.1" to an interface, say the loopback or ethernet
interface. From a *non-multicast* router, you can then ping 228.1.1.1
and hear replies from all "receivers".
HTH, Kym
