Usage Guidelines

Usage Scenario

If the remote device has a limited capability of receiving NA messages or the local device has a limited capability of processing neighbor solicitation (NS) messages, run the ipv6 nd na send rate-limit command on the local device to set a limit on the rate at which NA messages are sent. This prevents a failure to learn ND entries or incorrect deletion of ND entries caused by NA message discarding.

Configuration Impact

If the rate limit is set to a small value, address resolution becomes slow in the case of a large number of neighbor entries.

Example

# Set a limit on the rate at which NA messages are sent to 500 in the system view.
