Course Outline

  • Assignment and use of the Class D Multicast IP address space.
  • Mapping multicast MAC addresses (L2) to multicast IP addressses (L3).
  • An overview of the Real time Transport Protocol (RTP).
  • Comparison between the 3 versions of the Internet Group Management Protocol (IGMP) and their use in requesting RTP streams within VLANs.
  • IGMP snooping on a L2 network.
  • IGMP queriers and querier resilience.
  • The use of multicast routing using Protocol Independent Multicast (PIM) on an inter-VLAN and/or L3 routed network.
  • The difference between PIM operated in Dense Mode PIM-DM and in Sparse Mode (SM).
  • Registration of multicast streams with a Rendezvous Point (RP).
  • Important timers used in IGMP and PIM protocols.
  • Gateway resilience using Virtual Router Redundancy Protocol (VRRP) and mapping resilient multicast forwarding at L3 and L2 using the Rapid Spanning Tree Protocol (RSTP).
  • Important timers and parameters in VRRP and RSTP.
  • Operation and use of the multicast routing table to forward IP packets using a multicast destination IP address.
  • The differences between Any Source Multicast (ASM) and Source Specific Multicast (SSM).
  • Forwarding of multicast streams using the shortest path and shared trees.
  • Use of Reverse Path Forwarding for loop avoidance in multicast forwarding.
  • An overview of the Session Announcement Protocol (SAP) and it's use in describing and announcing RTP multicast streams that can be requested using IGMP.

Practical:

Wireshark will be used to analyse the multicast signalling (IGMP and SAP) and also the multicast media delivery (RTP).

  • Lab 1. Multicast Forwarding at L2 and IGMP Snooping.
  • Lab 2. Multicast Forwarding at L3 across VLANs using IGMP and PIM.
  • Lab 3. Announcement of multicast streams in L2/L3 networks using SAP and the mini-SAP Server.
  • Lab 4. Load balancing and failover of multicast streams carried in separate VLANs across a resilient Layer 2 network consisting of leaf (access) switches and 2 redundant spine (core) switches.
  • Lab 5: Multicast forwarding across VLAN boundaries in resilient Layer 3 networks consisting of leaf (access) switches and 2 redundant spine (core) switches.
  • Lab 6. Multicast forwarding over a routed L3 network using PIM-SM.

Requirements

Ideally delegates should also have attended a TCP/IP and IP Routing course (or have the equivalent experience).

Delegates must have a good understanding of Ethernet, forwarding of Ethernet Frames, IP and IP forwarding and gateway resilience using VRRP.
