Context
In routine maintenance, you can run the following commands in any view to check the running
status of PIM-SM.
Procedure
l Run the display pim ipv6 control-message counters [ message-type { assert | graft |
graft-ack | hello | join-prune | state-refresh | bsr } | interface interface-type interface-
number ]
*
command in any view to check the number of sent and received PIM-IPv6
control messages.
l Run the display pim ipv6 bsr-info command in any view to check information about the
BSR.
l Run the display pim ipv6 claimed-route [ ipv6-source-address ] command in any view
to check unicast routing information used by (S, G) and (*, G) entries in the PIM-SM routing
table.
l Run the display pim ipv6 rp-info [ ipv6-group-address ] command in any view to check
information about the RP to which the multicast group corresponds.
l Run the display pim ipv6 grafts command in any view to check the unacknowledged PIM-
IPv6 Graft messages.
l Run the display pim ipv6 interface [ interface-type interface-number | up | down ]
[ verbose ] command in any view to check information about PIM-IPv6 interfaces.
l Run the display pim ipv6 neighbor [ ipv6-link-local-address | interface interface-type
interface-number | verbose ]
*
command in any view to check information about PIM-IPv6
neighbors.
l Run the following commands in any view to check the PIM-IPv6 multicast routing table.
– display pim ipv6 routing-table [ ipv6-source-address [ mask mask-length ] | ipv6-
group-address [ mask mask-length ] | flags { act | del | exprune | ext | loc | niif |
nonbr | none | rpt | sg_rcvr | sgjoin | spt | swt | wc | upchg } | 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 } ]

When a fault occurs during the running of IPv6 PIM, run the debugging commands in the user
view and check the contents of sent and received packets for fault location.
Context
CAUTION
Debugging affects the performance of the system. So, after debugging, run the undo debugging
