protocols (Dynamic Profiles)


Hierarchy Level


Enable Internet Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD) Protocol on the router and configure interface-specific values on dynamic interfaces for each protocol.

PIM and MLD manage multicast groups by establishing, maintaining, and removing groups on a subnet. Multicast routing devices use these protocols to learn which groups have members on each of their attached physical networks. Enable IGMP for the router to receive IPv4 or IPv6 multicast traffic. Enable MLD for the router to receive IPv6 multicast traffic. MLD is needed only for IPv6 networks.

You can also use this statement to enable router advertisement for IPv6 Neighbor Discovery protocol and configure interface-specific values on dynamic interfaces.

You can configure these protocols in a dynamic client profile or a dynamic service profile.

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.


IGMP is disabled on the router. IGMP is automatically enabled on all broadcast interfaces when you configure Protocol Independent Multicast (PIM) or Distance Vector Multicast Routing Protocol (DVMRP).
