Configuring Control Parameters of the Multicast Forwarding Table

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.

Setting the Maximum Number of Entries in Multicast Forwarding Table: You can adjust the number of entries according to the actual networking and service performance to avoid the fault risk resulted from excessive entries.

Setting the Maximum Number of Downstream Nodes of a Multicast Forwarding Entry: A multicast device replicates a copy of multicast packets for each downstream interface. Then, you can set the number of downstream interfaces of a single forwarding entry and adjust the number of downstream interfaces according to the actual networking and service performance to release the burden on the multicast device.
