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

The Group Management Protocol allows any of the interfaces to become a receiver for the multicast stream. It allows testing the multicast routing and switching setups without using dedicated IGMP or MLD clients. The option has been available since RouterOS v7.4 and it supports IGMP v1, v2, v3 and MLD v1, v2 protocols.

📄️IGMP Proxy

The Internet Group Management Protocol (IGMP) proxy can implement multicast routing. It is forwarding IGMP frames and is commonly used when there is no need for a more advanced protocol like PIM.

📄️PIM-SM

IP Multicast is a technology that allows data to be efficiently shared with many recipients over the Internet. Senders transmit their data to a specific multicast IP address, and receivers indicate their interest in receiving data sent to that address. The network then takes care of delivering the data from senders to receivers.
