Demo 4.1 - PIM Sparse Mode on IOS Routers Part 1

In this CCIE and JNCIE IP Multicast demo we cover PIM Sparse Mode on IOS routers in detail, using detailed packet captures. Please download the topology file from https://www.dropbox.com/sh/124zmocrwp... to follow along with the videos. The scenarios covered include: IGMP signaling Multicast Receivers present without any Multicast Sources (PIM Sparse Mode (*,G) Joins for the Rendezvous Point Tree (RPT) terminating at the RP (Rendezvous Point) Source signaling by the Multicast Source (MC message reception by the FHR) but no Multicast Receivers present ((S,G) states on the FHR and the RP via the PIM Sparse Mode (PIM-SM) Register message PIM Sparse-Mode topics relevant to CCIE and JNCIE candidates include: The PIM Register Tunnel abstraction (PIM Encap Tunnel and PIM Decap Tunnel abstraction in Cisco IOS routers) Presence and need for PIM Encap Tunnel and PIM Decap Tunnel on Rendezvous Point (RP) Presence and need for PIM Encap Tunnel on all PIM routers PIM Sparse Mode(Protocol Independent Multicast Sparse-mode) neighbor discovery mechanism How does PIM-SM (PIM Sparse Mode) use Hello messages to exchange TLV options PIM-SM (Protocol Independent Multicast Sparse Mode) Hello message format and options important to CCIE and JNCIE candidates: -- Hold Time for dead neighbor discovery -- Generation ID (GenID) for PIM Sparse Mode (PIM-SM) Graceful Restart -- DR Priority for PIM Sparse Mode (PIM-SM) Designated Router (DR election) -- Cisco proprietary option 65004 (RPF Proxy Vector) and how to disable it in PIM Sparse Mode (PIM-SM) How PIM-SM (PIM Sparse Mode) Designated Router (DR) election process Why is the DR (Designated Router) election important to PIM-SM (PIM Sparse Mode) How do the RP and the LHRs signal (S,G) and (*,G) states (SPT, RPT) using PIM Join/Prune messages In depth analysis of the PIM Join/Prune message with packet captures Structure of the PIM Join/Prune message How does the LHR signal the (*,G) (Rendezvous Point Tree or RPT) towards the Rendezvous Point (RP) The contents of the PIM Join message containing the (*,G) or RPT signaling How does the LHR populate the various fields of the PIM Join/Prune (*,G) message What are the Wildcard (WC) and RPT bits and what is their meaning in a PIM (*,G) Join message How does PIM leverage the same basic Join/Prune message in PIM Sparse Mode to signal both (S, G) and (*,G) trees How do the Middle Hop Routers (MHRs) process the PIM Join/Prune messages) The final state of the (*,G) tree on all the routers along with the identification of IIF (Incoming Interface) and the OIL (Outgoing Interface List) How an FHR communicates to the Rendezvous Point about an active (S,G) multicast source The PIM (Protocol Independent Message) Registration process The contents of the PIM Register message The concept of the PIM Null-Register message in PIM Sparse Mode The contents of the PIM Null-Register message in PIM Sparse Mode The concept of the PIM Register-Stop message in PIM Sparse Mode The contents of the PIM Register-Stop message in PIM Sparse Mode PIM Register message packet format deep dive PIM Register tunnel concept in PIM Sparse Mode How the PIM Register Tunnel is a Multipoint-to-Point tunnel in PIM Sparse Mode How the Rendezvous Point (RP) react to the receipt of a PIM Register Message in PIM Sparse Mode
