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.
Testimonials
Trainer was very sophisticated, had a lot of knowledge and knew what he was talking about. The organization of the day was also very good (breaks between the "lessons").
Martyna Antonowicz, ATOS PGS sp. z o.o.
Basic knowledge was presented in very granular way.
Martyna Antonowicz, ATOS PGS sp. z o.o.
Trainer is well prepared and dedicated in making us understand. Well done.
Alan Lye - SBS Transit Ltd
First of all it was very interesting practically for all topics covered by this training. Well balanced with theory, practise labs and breaks. Some of tips and tricks I have introduced to my work yet.
Dawid Woźny - Martyna Antonowicz, ATOS PGS sp. z o.o.
Course was very interesting and help me understood thoroughly protocols construction. I am very glad that i attended with this course.
Martyna Antonowicz, ATOS PGS sp. z o.o.
That the Wojciech Wójcik knowledge is really huge.
Kornel - Martyna Antonowicz, ATOS PGS sp. z o.o.
trainer listen to participants
Bartosz - Martyna Antonowicz, ATOS PGS sp. z o.o.
The exercises and analysis portion is very enriching and enlightening.
