Usage Guidelines
Usage Scenario
Excessive multicast forwarding entries will exhaust the memory of the wireless access controller. To prevent this problem, use the multicast forwarding-table route-limit command to limit the number of entries in the multicast forwarding table.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
Precautions
If the limit on the number of entries in the multicast forwarding table is set after multicast services are deployed on a wireless access controller, ensure that the limit on the number of entries in the multicast forwarding table is equal to or greater than the number of current forwarding entries. Otherwise, faults may occur.
You are recommended to limit the number of entries in the multicast forwarding table according to the actual network environment before the wireless access controller operates multicast services.
- Entries are added to the multicast forwarding table after the existing entries age out.
- The reset multicast forwarding-table all command is run.
