Context
NOTE
PIM-SM and PIM-DM cannot be enabled on an interface at the same time. The PIM mode must be the
same on all the interfaces of the same instance. When switches are distributed in different PIM-DM
domains, enable PIM-SM on all non-boundary interfaces.
Do as follows on the switch:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
The interface can be a VLANIF interface, or an Loopback interface.
Step 3 Run:
pim dm
PIM-DM is enabled.
After PIM-DM is enabled on the interface and the PIM neighbor relationship is set up between
switches, the protocol packets sent by the PIM neighbors can be processed. You can run the
undo pim dm command to disable PIM-DM on the interface.
----End
5.3.4 Checking the Configuration
After PIM-DM is configured successfully, you can check information about the PIM interface,
PIM neighbor, and PIM routing table through commands..
Procedure
l Run the command display pim [ vpn-instance vpn-instance-name | all-instance ]
interface [ interface-type interface-number | up | down ] [ verbose ] to check PIM on
interfaces of the public network, VPN instance, or all instances.
l Run the command display pim [ vpn-instance vpn-instance-name | all-instance ]
neighbor [ neighbor-address | interface interface-type interface-number | verbose ]
*
to
check PIM neighbors of the public network, VPN instance, or all instances.
l Run the following commands to check the PIM routing table of the public network, VPN
instance, or all instances.
– 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 ] ]
