Usage Guidelines

Usage Scenario

If the remote device has a limited capability of receiving RA messages or the local device has a limited capability of processing router solicitation (RS) messages, run the ipv6 nd ra send rate-limit command on the local device to set a limit on the rate at which RA messages are sent. This prevents a host from failing to update the default routing information.

Configuration Impact

If the rate limit is set to a small value, the rate at which a host updates the default routing information becomes slow.

Example

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