Configuring IGMP and IGMP Proxy

IP hosts use Internet Group Management Protocol (IGMP) in IPv4 to report their multicast group memberships to neighboring routers. Similarly, multicast routers, such as an E Series router, use IGMP to discover which of their hosts belong to multicast groups.

This chapter describes how to configure IGMP for IP multicast on an E Series router; it contains the following sections:

• IGMP Overview
• IGMP Platform Considerations
• IGMP References
• Static and Dynamic IGMP Interfaces
• Before You Begin Configuring IGMP
• Enabling IGMP on an Interface
• Configuring IGMP Settings for an Interface
• Configuring Multicast Groups for IGMP
• Access Node Control Protocol for IGMP
• SSM Mapping
• Overview of Limiting the Number of Accepted IGMP Groups
• IGMP Traffic Overview
• Explicit Host Tracking
• Configuring IGMP Attributes
• Example: Accepting IGMP Reports from Remote Subnetworks
• IGMP Proxy Overview
• Configuring IGMP Proxy
• Establishing the IGMP Proxy Baseline
