Huawei quidway s7700 - Checking the Configuration; Adjusting Control Parameters for Assert

The interval for retransmitting Graft messages is set.
If the local switch does not receive any Graft-Ack message from the upstream switch in a
specified period, it resends a Graft message.
----End
5.8.3 Checking the Configuration
After the control parameters for graft are adjusted, you can check information about the
unacknowledged PIM-DM graft, PIM interface, and PIM routing table and statistics about PIM
control messages through commands.
Procedure
l Run the display pim [ vpn-instance vpn-instance-name | all-instance ] interface
[ interface-type interface-number | up | down ] [ verbose ] command to check PIM on an
interface.
l Run the display pim [ vpn-instance vpn-instance-name | all-instance ] grafts command
to check an unacknowledged PIM-DM graft.
l Run the display pim [ vpn-instance vpn-instance-name | all-instance ] 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 the
sent or received PIM control messages.
l Run the following commands to check the PIM routing table.
– display pim { vpn-instance vpn-instance-name | all-instance } routing-table [ group-
address [ mask { group-mask-length | group-mask } ] | source-address [ mask { source-
mask-length | source-mask } ] | incoming-interface { interface-type interface-
number | register } | outgoing-interface { include | exclude | match } { interface-type
interface-number | register | none } | mode { dm | sm | ssm } | flags flag-value | fsm ]
*
[ outgoing-interface-number [ number ] ]
– display pim routing-table [ group-address [ mask { group-mask-length | group-
mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-
interface { interface-type interface-number | register } | outgoing-interface
{ include | exclude | match } { interface-type interface-number | vpn-instance vpn-
instance-name | register | none } | mode { dm | sm | ssm } | flags flag-value | fsm ]
*
[ outgoing-interface-number [ number ] ]
– display pim [ vpn-instance vpn-instance-name | all-instance ] routing-table brief
[ group-address [ mask { group-mask-length | group-mask } ] | source-address
[ mask { source-mask-length | source-mask } ] | incoming-interface { interface-type
interface-number | register } ]

5.9 Adjusting Control Parameters for Assert
If a multicast device can receive multicast data through an downstream interface, this indicates
that other upstream devices exist in this network segment. The device then sends an Assert
message through the downstream interface to take part in the election of the unique upstream
device.
