Users are accessing streaming application from the internet for training purpose. We have internet links in the data center and users are using proxy server to access internet.
Internet links are connected in Router 3845, core switches are C6509 & access switches C2960.
Our requirement is to configure multicasting to reduce bandwidth while using the webcast application.
In this scenario which one is preferred PIM SPARSE or PIM DENSE mode? Is any thing need to configure in L2 switches?
Thanks in advance
