Today launches the first of many of our new INE Video Blog series.  Our first video covers the advanced design issues with running Multicast and Auto-RP over NBMA networks such as Frame-Relay Hub-and-Spoke.  Specifically this video focuses on possible solutions such as sparse-dense mode, sparse-mode with auto-rp listener, sparse-mode with a default RP placement, and PIM Join issues related to point-to-point vs multipoint interfaces and their underlying IGP protocols.

A pretty important topic that is very easy to overlook when studying multicast is the PIM Assert Mechanism.  After working with the TechEdit Team in the IEOC it is obvious that more than just a handful of students are confused about what this mechanism does and how it works. In this blog post (the first of many dedicated to multicasting), we will examine the PIM Assert mechanism and put this topic behind us in our preparation in mastering multicast. In Figure 1, R1 and R4 have a route to the... Read More

Bootstrap router or BSR is standard-based protocol available with PIMv2. The protocol performs the same function as Cisco’s proprietary Auto-RP, i.e. disseminates RP information. Both protocols use the concept of candidate RP, i.e the router that is announcing itself as a potential RP. Unlike Auto-RP, BSR does not use any dense-mode groups to flood candidate RP and RP mapping information. Instead, the information is flooded using PIM messages, on hop-by-hop basis. The flooding procedure... Read More
