Hi all,
I am having difficulty with setting up multicast auto rp over FR with
sparse mode.
I can't ping any multicast group configured on R3, R4, R6.
R4

| | |
R7---R5 R6 R3
R3, R4,R5 and R6 are connected over FR point-to-multipoint connection with
R4 is the hub.
R7 connected to R5 via ethernet link.
R3 is configured with ip igmp join-group 224.8.8.3
R4 is configured with ip igmp join-group 224.8.8.4
R5 is configured with ip igmp join-group 224.8.8.5
R6 is configured with ip igmp join-group 224.8.8.6
R4 is configured as a mapping agent. When configure R7 as an C-RP I was able
to ping all group above.
However when I configure R4 as the C-RP, I can't ping any of the group from
R7.
Below are the configurations
