multicast forwarding-table route-limit
Function
The multicast forwarding-table route-limit command limits the capacity of the multicast forwarding table, that is, set the maximum number of entries in the forwarding table.
The undo multicast forwarding-table route-limit command restores the default value of the capacity.
Parameters
| Parameter | Description | Value |
|---|---|---|
limit |
Indicates the maximum number of entries in the multicast forwarding table |
The value is an integer ranging from 0 to 2048. The number varies according to products. |
Usage Guidelines
- Entries are added to the multicast forwarding table after the existing entries age out.
- The reset multicast forwarding-table all command is run.
If the maximum number of routes in the multicast forwarding table is set after multicast services are operated on a FW, ensure that the maximum 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 capacity of the multicast forwarding table according to the actual network environment before the FW operates multicast services.
Example
# Set the maximum number of the entries in the forwarding table of the public network instance to 1024.
