Usage Guidelines

After configuring the maximum number of IPv6 neighbors, you must use the write-memory and reload commands to place the change into effect.

When using the forwarding-profile command, if profile3 is selected, it is recommended to configure the maximum number of IPv6 neighbors to 65536. Refer to the forwarding-profile command for more information.

The no form of the command removes the configured maximum number of IPv6 neighbors and restores the default.
