GMP

Group Management Protocol (IGMP/MLD) interfaces and memberships (`/routing gmp`).

Tools

list_gmp_interfaces

List GMP Interfaces · Risk: read

Lists GMP interface records (/routing gmp interface) — returns per-interface querier role, protocol version, and timer state for RouterOS's Group Management Protocol layer (IGMP for IPv4, MLD for IPv6), which PIM-SM and IGMP-proxy use to discover downstream receiver group memberships. For the actual multicast groups joined on each interface use list_gmp_group_memberships. Read-only; requires RouterOS v7 with the routing/multicast package.

No tool-specific parameters.

list_gmp_group_memberships

List GMP Group Memberships · Risk: read

Lists GMP group membership records (/routing gmp group) — returns the multicast groups currently joined per interface as learned from downstream IGMP (IPv4) or MLD (IPv6) reports; the source of truth for which segments want which groups, used by PIM-SM and IGMP-proxy for forwarding decisions. For per-interface querier role and timer state use list_gmp_interfaces. Accepts optional filters: interface_filter (exact interface name) and group_filter (regex match on multicast group address). Read-only; requires RouterOS v7 with the routing/multicast package.

ParameterRequiredDefinition
interface_filterNoShow only memberships on this interface {"type":"string"}
group_filterNoRegex match on the multicast group address {"type":"string"}
