Usage
Information
The maximum number of multicast entries allowed on each line card is determined by the CAM
profile. Multicast routes are stored in the IN-V6-McastFib CAM region, which has a fixed number of
entries. Any limit configured via the CLI is superseded by this hardware limit. The opposite is also
true; the CAM might not be exhausted at the time the CLI-configured route limit is reached.
