Re: INE ver-4 vol-1 Multicasting lab (Dense-mode)

Hi Syed,

To help verify this problem the following could help:

1) Check that pim neighbors are formed along the way between SW1 -->SW2.
2) Debug ip mpacket could help also show what is really going on to the
multicast packets; plus if any RPF failures exist along the path.

While going through this procedure you should be able to understand what is
going wrong and correct it.

Best Regards,

Karim Jamali
