Multicast Routing Protocols

This section covers RouterOS multicast routing protocols and related group-management features. Use it to configure IGMP Proxy, PIM-SM, and multicast group behavior.

📄️Group Management Protocol

Group Management Protocol enables interfaces to receive multicast streams without dedicated clients, supporting IGMP and MLD protocols. It allows testing multicast routing by sending membership reports and responding to queries, with automatic cleanup when disabled.

📄️IGMP Proxy

The IGMP Proxy feature in RouterOS enables multicast routing by forwarding IGMP frames, offering a simpler alternative to PIM-SM for certain topologies. It supports basic multicast forwarding with minimal resource usage but lacks support for complex routing setups and loop detection.

📄️PIM-SM

This page introduces IP Multicast and Protocol Independent Multicast - Sparse Mode (PIM-SM) in MikroTik RouterOS, explaining how it enables efficient data sharing across networks. It covers basic PIM-SM configuration for multicast routing between separate interfaces, including interface setup, PIM instance creation, and IGMP integration.
