Monitoring the Running Status of IPv6 PIM

Procedure

• Run the display pim ipv6 bsr-info command to check information about the BSR in the IPv6 PIM-SM domain.
• Run the display pim ipv6 rp-info [ ipv6-group-address ] command to check information about RPs of the multicast group.
• Run the display pim ipv6 claimed-route [ ipv6-source-address ] command to check unicast routes used by IPv6 PIM.
• Run the following commands to check the number of sent and received IPv6 PIM control packets.

  • display pim ipv6 control-message counters message-type { probe | register | register-stop | crp }

  • display pim ipv6 control-message counters [ message-type { assert | graft | graft-ack | hello | join-prune | state-refresh | bsr } | interface interface-type interface-number ] ^*

• Run the display pim ipv6 interface [ interface-type interface-number | up | down ] [ verbose ] command to check IPv6 PIM information on an interface.
• Run the display pim ipv6 neighbor [ ipv6-link-local-address | interface interface-type interface-number | verbose ] ^* command to check information about IPv6 PIM neighbors.
• Run the following commands to check the IPv6 PIM routing table.
  • display pim ipv6 routing-table [ ipv6-source-address [ mask mask-length ] | ipv6-group-address [ mask mask-length ] | flags flag-value | fsm | incoming-interface { interface-type interface-number | register } | mode { dm | sm | ssm } | outgoing-interface { exclude | include | match } { interface-type interface-number | none | register } ] ^* [ outgoing-interface-number [ number ] ]

  • display pim ipv6 routing-table brief [ ipv6-source-address [ mask mask-length ] | ipv6-group-address [ mask mask-length ] | incoming-interface { interface-type interface-number | register } ] ^*

• Run the following commands to check the statistics about the invalid IPv6 PIM packets received by the device.
  • display pim ipv6 invalid-packet [ interface interface-type interface-number | message-type { assert | bsr | hello | join-prune | graft | graft-ack | state-refresh } ] ^*
  • display pim ipv6 invalid-packet message-type { crp | register | register-stop }
