Usage Guidelines

Usage Scenario

You can run the display pim ipv6 invalid-packet command to view statistics and details of invalid IPv6 PIM messages for fault location and rectification.

If IPv6 PIM entries fail to be generated on a multicast network, you can run the display pim ipv6 invalid-packet command first to check whether devices have received invalid IPv6 PIM messages.

You can run the display pim ipv6 invalid-packet command to view statistics about invalid IPv6 PIM messages received by a specified interface.

Example

The actual command output varies according to the device. The command output here is only an example.
