Limit the Number of IPv6 Multicast Routes
You can limit the total number of IPv6 multicast routes on the system. 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superseded by this hardware limit.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.
