CCIE R&S 400-101 V5.1 Written Exam: Implement and Troubleshoot IGMP

In this article, I will be discussing Cisco Implement and Troubleshoot IGMP as part of Layer 2 Technologies and Layer 2 Multicast CCIE Routing and Switching (R&S) V5.1 exam blueprint topics.

Layer 2 Multicast

  • Implement and troubleshoot IGMP
    • IGMPv1, IGMPv2, IGMPv3
    • IGMP snooping
    • IGMP querier
    • IGMP filter
    • IGMP proxy

Let me summarize some of the key takeaways related to Implement and Troubleshoot IGMP as relevant to CCIE Routing and Switching (R&S) V5.1 written exam blueprint topics.

Implement and Troubleshoot IGMP Exam Essentials

  • IGMPv3 adds support for source filtering, that is, the ability for a system to report interest in receiving packets from specific source addresses, or from all but specific source addresses sent to a specific multicast address. This feature is also known as Source Specific Multicast (SSM).
  • IGMP filtering allows users to configure filters on a switch virtual interface (SVI), a per-port, or a per-port per-VLAN basis to control the propagation of IGMP traffic through the network.
  • When you enter an IGMP filtering command, a user policy is applied to a Layer 3 SVI interface, a Layer 2 port, or a particular VLAN on a Layer 2 trunk port.

I sincerely hope that you found this article and video helpful. Please post your questions or suggestions in the comments and tell me how you are preparing for your CCIE Routing and Switching (R&S) V5.1 written and lab exams.
