Configuring Multicast Forwarding Cache Limits

To configure multicast forwarding cache limits, include the following statements:

You can include these statements at the following hierarchy levels:

• [edit routing-options]
• [edit logical-systems logical-system-name routing-options]

For an overview of logical systems and a detailed example of logical system configuration, see the logical systems chapter of the Junos Feature Guide.

By default, there are no limits on the number of multicast forwarding cache entries.

Specify a value for the threshold at which to suppress new multicast forwarding cache entries and an optional reuse value for the threshold at which the router begins to create new multicast forwarding cache entries. The range for both is from 1 through 200,000. If configured, the reuse value should be less than the suppression threshold value. The suppression value is mandatory. If you do not specify the optional reuse value, then the number of multicast forwarding cache entries is limited to the suppression value. A new entry is created as soon as the number of multicast forwarding cache entries falls below the suppression value.
