Good day
I need your help on the below.
i have multicast running in sparse mode on the loopback 1 interfaces and
the serial links of the Frame Relay with R2 the hub.
I am able to ping both groups 225.0.0.2 and 225.0.0.5 from R2 and R5 but
not from R6.
below are the interfaces config and the output of the debug ip mrouting
command. Thank you in advance.
