Certified Allied Telesis Expert - Multicast - lectures and labs - 2 days
- Layer 2 and Layer 3 multicast
- PIM dense mode
- PIM sparse mode
- Source-specific multicast
This course is designed to teach attendees how to design, install and perform advanced multicast configuration on the Layer 2 and Layer 3 core switches. The participants will have the opportunity to practice in a lab environment.
-
Layer 2 and Layer 3 multicast
This module describes Layer 2 and Layer 3 multicasting: the structure of a multicast network, the role of routers and switches in a multicast network, the differences between unicast forwarding and multicast forwarding. Candidates will study creating a forwarding tree in a Layer 2 multicast network using IGMP snooping and IGMP query and Layer 3 multicast forwarding with PIM sparse mode and Layer 3 multicast forwarding with PIM dense mode.
-
PIM dense mode
The module includes an overview of operations with PIM-DM, neighbor discovery, pruning and grafting, state refreshes, assert mechanism, generation ID and packet formats.
-
PIM sparse mode
This presentation includes a comparison between dense mode and sparse mode, an overview of PIM sparse mode, as well as BSR election and RP distribution, registering streams, tree information bases, obtaining a stream, joining and pruning PIM-SM packet formats.
-
Source-specific multicast
Overview of source-specific multicasting, changes made to IGMP and PIM to support SSM, terminology, the address range used and how to use older versions of IGMP with source-specific multicasting.
