Multicast over FR

[ikizoo4]

Hello

I'd like to configure multicast PIM sparse-dense mode on router A, B, C, which means there are some sparse mode groups and some dense mode groups, for sparse mode use PIMv2 BSR. Sparse-dense mode is enabled on all serial interfaces.

Router A's serial interface is configured as FR multipoint.

Q. FR multipoint interface does not support multicast or broadcast, how can i fix this problem?

Hello,

one way to solve this problem would be to configure subinterfaces on your hub router for the connections to both spokes. Is there a restriction in your setup where you can only use the physical interface on your hub router ?

Hi

Thanks for answering, it is not allowed to use point to point subinterface.

Hi,

Some resource saying that we can use "ip pim mode nbma" and "ip pim sparse-dense " at same interface.

and some other saying that "ip pim mode nbma" works with only "ip pim sparse"...any idea about this?
