The system synchronously maintains multiple multicast routing
protocols, and controls multicast routing and forwarding through the
information exchanged between the control plane and the forwarding
plane.
This section describes the application of the RPF check, multicast load splitting, route selection based on the longest match principle, and multicast boundary in multicast forwarding.
Configuring a multicast routing policy involves configuring the longest match of the multicast route, configuring multicast load splitting, and setting a multicast load splitting weight.
During network planning, you can restrict the capacity of the forwarding table on a multicast device, such as the maximum number of entries in the multicast forwarding table and the maximum number of downstream interfaces of multicast forwarding entries. In this manner, traffic load on the multicast device is released and the fault risk resulted from excessive entries can be avoided.
A multicast forwarding boundary can be configured for a multicast group on a multicast FW interface to limit the range within which multicast data for the multicast group can be forwarded.
This section describes how to configure the maximum number of invalid multicast protocol packets that a device can store. This configuration helps locate and rectify faults.
Configuring multicast routing and forwarding include how to configure a multicast static route, multicast routing policy, multicast forwarding range, and multicast forwarding table capacity.
