Configuring the Maximum Number of Invalid IPv4 Multicast Protocol Packets That a Router Can Store

Configuring the Maximum Number of Invalid IPv4 Multicast Protocol Packets That a Router Can Store

Context

If multicast forwarding entries or Multicast Source Discovery Protocol (MSDP) peer relationships cannot be established on a network, you can configure the maximum number of invalid multicast protocol packets that the routers can store. Then check statistics and details about invalid multicast packets for troubleshooting.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the multicast invalid-packet { igmp | msdp | pim } max-count max-number command to set the maximum number of invalid multicast protocol packets that the router can store.

    By default, a router can store a maximum of 10 invalid packets for each multicast protocol.

Verifying the Configuration

After completing the configuration, run the following commands to check the maximum number of invalid IPv4 multicast protocol packets that can be saved and statistics about invalid multicast protocol packets:

  • Run the display current-configuration | include multicast invalid-packet command to check the maximum number of invalid multicast protocol packets that the router can store.

  • Run the following commands to check the statistics about various invalid multicast protocol packets saved on the router:
    • Run the display igmp [ vpn-instance vpn-instance-name | all-instance ] invalid-packet [ interface interface-type interface-number | message-type { leave | query | report } ] * command to check statistics about invalid Internet Group Management Protocol (IGMP) packets saved on the router.

    • Run the display msdp [ vpn-instance vpn-instance-name | all-instance ] invalid-packet [ peer peer-address | message-type { keepalive | notification | sa-request | sa-response | source-active } ] * command to check statistics about invalid MSDP packets saved on the router.

    • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] invalid-packet [ interface interface-type interface-number | message-type { assert | bsr | hello | join-prune | graft | graft-ack | state-refresh } ] * command or display pim [ vpn-instance vpn-instance-name | all-instance ] invalid-packet message-type { crp | register | register-stop } command to check statistics about invalid Protocol Independent Multicast (PIM) packets saved on the router.

  • Run the following commands to check detailed information about a specified number of latest invalid multicast protocol packets received by the router:
    • Run the display igmp invalid-packet [ packet-number ] verbose command to check details information about a specified number of latest invalid IGMP packets received by the router.

    • Run the display msdp invalid-packet [ packet-number ] verbose command to check details information about a specified number of latest invalid MSDP packets received by the router.

    • Run the display pim invalid-packet [ packet-number ] verbose command to check details information about a specified number of latest invalid PIM packets received by the router.
