Limiting the number of entries in the IP multicast forwarding table
The S9300 creates and maintains a forwarding entry for each received multicast packet.
Excessive multicast forwarding entries, however, may use up the memory of the S9300.
You can set the maximum number of entries in the multicast forwarding table on the
S9300. Limiting the number of entries according to the actual networking and service
performance can avoid faults caused by excessive entries.
Limiting the number of downstream nodes of a single forwarding entry
An S9300 replicates a multicast packet for each downstream node and sends it out. Each
downstream node is a branch of a multicast distribution tree. The number of downstream
nodes determines the maximum scale of an MDT and the service range. You can define
the number of downstream nodes of a single forwarding entry on the S9300. Limiting the
number of downstream nodes according to the actual networking and service performance
can ease the processing pressure of the system and control the service range.
