The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
pim ipv6 holdtime assert interval
The period for keeping the Assert state is set.
The switch that fails in the election prohibits its downstream interface from forwarding
multicast data.
After the Holdtime timer times out, the downstream interface continues to forward
packets.

12.9.3 Checking the Configuration
After the control parameters for assert are adjusted, you can check information about the PIM
interface and the PIM routing table and statistics about PIM control messages through
commands.
Procedure
l Run the display pim ipv6 interface [ interface-type interface-number | up | down ]
[ verbose ] command to check information about PIM-IPv6 interfaces.
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 to check the number of sent and received PIM-IPv6 control messages.
l Run the following commands 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 } ]
*

12.10 Configuring PIM-IPv6 Silent
The interface directly connecting a multicast device to a user host needs to be enabled with PIM.
In this case, some malicious hosts may simulate a large number of PIM Hello messages and send
the messages to the interface for processing. As a result, the multicast device is suspended. To
avoid the preceding case, you can set the interface to be in the PIM Silent state.
