IPv6 Multicast Policies e IPv6 Multicast Policies is available only on platform: • Limit the Number of IPv6 Multicast Routes on page 451 • Prevent an IPv6 Neighbor from Forming an Adjacency on page 452 • Prevent an IPv6 Source from Registering with the RP on page 452 • Prevent an IPv6 PIM Router from Processing an IPv6 Join on page 452 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 Any limit configured via the CLI is superseded by this hardware limit.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. Task Limit the total number of IPv6 multicast routes on the system. Command Syntax ipv6 multicast-limit Range: 1-50000 Default: 15000 Command Mode CONFIGURATION Multicast Features | 451
