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.
Abstract This publication illustrates some common techniques for troubleshooting multicast issues in IP networks. Common problems and their causes are discussed, troubleshooting techniques demonstrated. PIM Sparse mode is used for most of the examples, due to the fact that this is the most complicated mode of multicast signaling. The suggested troubleshooting approach separates control plane from data-plane troubleshooting and heavily relies on the mroute command for the control-plane...
