Nki,
You may have to explain what, you intend to do more....
Generally, multicast sources or senders announce themselves when they enter
the network.eg a multimedia server can announce its present on the network
eg by sending its stream on multicast address 239.1.1.1 PCs on the network
that want to receive feeds from the server have to join the mulicast group
239.1.1.1.
In the absence of a multicast sender, you can simply configure your
interface to join a multicast group:
!
Interface fa0/0
ip igmp join-group 239.1.1.1
!
OR
Interface fa0/0
ip igmp static-group 239.1.1.1
!
Option 1, In addition to forwarding traffic to multicast source 239.1.1.1,
will process those traffic, so it will response to ping send to that
address; but option 2, will forward multicast traffic to the source without
processing them.
I see, that you have enabled ip pim sparse-mode, below. For starters, try
using 'ip pim sparse-dense-mode' or 'ip pim dense-mode'. Sparse mode get
things a little messy and will require some extral configurations. There is
no concept of "source" per say in sparse mode, the root or pseudo-source of
the multicast tree is at the Rendezvous Point or RP and it is based on a
shared tree (*,G).
I do not know if this answered your question, but you can always explain
more better what you are looking for.
