If the basic ACL is configured, only the packets with the source addresses that pass the filtering
are forwarded.
If the advanced ACL is configured, only the packets with the source addresses and group
addresses that pass the filtering are forwarded.
NOTE
l If acl-number | acl-name acl-name is specified in the source-policy command, the multicast packets
with the specified source address or source and group addresses are forwarded.
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.

6.4.4 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 } ]

6.5 Adjusting Control Parameters of the C-RP and C-BSR
If a dynamic RP is used, you can adjust parameters of C-RPs and C-BSR as required. If there is
no special requirement, default values are recommended.
6.5.1 Establishing the Configuration Task
If dynamic RP is used, after basic functions of PIM-SM are configured, you can adjust parameters
of the C-RP and C-BSR, configure a BSR boundary, and set valid address ranges for BSRs and
C-RPs.
