Usage Guidelines
Usage Scenario
Through the output of the display icmpv6 statistics command displays the statistics about sent and received ICMPv6 error messages and four types of ICMPv6 messages in the neighbor discovery mechanism, including RS, RA, NS, and NA messages.
In the ping IPv6 operation, you can run the display icmpv6 statistics command on the device and check whether the total number of sent and received messages on the device is correct based on the command output.Precautions
The total number of messages received by the Router includes the number of messages forwarded by the Router, the number of messages delivered by the Router to the upper layer, and the number of messages discarded by the Router.
Example
The actual command output varies according to the device. The command output here is only an example.
