NOTE
l If acl-number | acl-name acl-name is specified in the source-policy command and ACL rules are
created, only the multicast packets whose source addresses match the ACL rules are permitted.
l If acl-number | acl-name acl-name is specified in the source-policy command and no ACL rule is
created, the multicast packets with any source addresses are not forwarded.
l The source-policy command does not filter the static (S, G) entries and the PIM entries of the Join
messages received from private networks.
----End
5.4.4 Checking the Configuration
After the control parameters of a multicast source are adjusted, you can run commands to check
entries in the PIM routing table.
Procedure
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 } ]

5.5 Adjusting Control Parameters for Maintaining Neighbor
Relationships
PIM devices exchange Hello messages to set up neighbor relationships and negotiate various
control parameters for controlling the neighbor relationships.
5.5.1 Establishing the Configuration Task
After basic functions of PIM-DM are configured, you can adjust related parameters of Hello
messages for controlling the neighbor relationships, and configure the neighbor filtering function
to enhance security as required.
