Multicast PIM Sparse

[agapitca19]

Hi,

Does multicast need a routing protocol to work?

What if some switches along the path are using SVIs for connectivity,will it still work?

Thanks!

Hello,

if SVIs are involved, you need a multicast routing protocol, such as PIM.

Cisco has a pretty comprehensive paper on the subject:

I understand that interfaces involved on multicast have to be configured,which in our case sparse mode and the other basic info about multicasting.

what i want to clarify is, if it is a requirement for a routing protocol like eigrp or ospf running on all switches/routers to make PIM works.

Thanks

Sorry for the misunderstanding. You need layer 3 connectivity between the devices where multicast is deployed. That does not have to be a routing protocol. Static routes are sufficient. There is no relationship between e.g. EIGRP or OSPF and multicast.

Does that clarify your question ?

No problem and yes that clarified my question.

Thanks!
