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.
