mode, and source list. Such an entry is a collection of members in the same multicast group on each downstream interface. A proxy device performs host functions on the upstream interface based on the database. It responds to queries according to the information in the database or sends join/leave messages when the database changes. On the other hand, the proxy device performs router functions on the downstream interfaces by participating in the querier election, sending queries, and maintaining memberships based on the reports. Protocols and standards • RFC 1112, Host Extensions for IP Multicasting • RFC 2236, Internet Group Management Protocol, Version 2 • RFC 3376, Internet Group Management Protocol, Version 3 • RFC 4605, Internet Group Management Protocol (IGMP)/Multicast Listener Discovery (MLD)-Based Multicast Forwarding ("IGMP/MLD Proxying") IGMP configuration task list Task Configuring basic IGMP functions Adjusting IGMP performance Configuring IGMP SSM mapping Configuring IGMP proxying Remarks Enabling IGMP Required Configuring IGMP versions Optional Configuring static joining Optional Configuring a multicast group filter Optional Setting the maximum number of multicast groups that an interface can join Optional Configuring Router-Alert option handling methods Optional Configuring IGMP query and response parameters Optional Configuring IGMP fast-leave processing Optional Enabling the IGMP host tracking function Optional Setting the DSCP value for IGMP messages Optional Enabling SSM mapping Optional Configuring SSM mappings Optional Enabling IGMP proxying Optional Configuring multicast forwarding on a downstream interface Optional For the configuration tasks in this section: • In IGMP view, the configuration is effective on all interfaces.
