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 Any limit configured via the CLI is superseded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.
ipv6 multicast-routing
e
Enable IPv6 multicast forwarding.
Syntax ipv6 multicast-routing
To disable multicast forwarding, enter no ipv6 multicast-routing.
Defaults
Disabled
