interface (Multicast Static Routes)


Hierarchy Level


Enable multicast traffic on an interface.

By default, multicast packets are forwarded by enabling Protocol Independent Multicast (PIM) on an interface. PIM adds multicast routes into the routing table.

You can also configure multicast packets to be forwarded over a static route, such as a static route associated with an LSP next hop. Multicast packets are accepted on an interface and forwarded over a static route in the forwarding table. This is useful when you want to enable multicast traffic on a specific interface without configuring PIM on the interface.

You cannot enable multicast traffic on an interface and configure PIM on the same interface simultaneously.

Static routes must be configured before you can enable multicast on an interface. Configuring the interface statement alone does not install any routes into the routing table. This feature relies on the static route configuration.
