6.3.12 Configuring the RP to Filter Incoming Registration Packets
In the PIM-SM network, the register packet filtering mechanism helps an RP to decide
the groups a source sends packets to, namely the packets to receive and forward.
Please perform the following configurations in PIM view.
Table 6-14 Configuring the RP to filter incoming registration packets
Operation Command
Configure the RP to filter the incoming
registration packets
register-policy acl-number
Remove filtering configuration
undo register-policy
If the entry (S, G) of a source group is denied or not defined by the ACL, or there is no
ACL, the RP will send RegisterStop information to the DR to stop the registration of this
multicast data stream.
Caution:
Only the register packets matching the ACL permit clause will be accepted by the RP.
Specifying an undefined ACL will cause the RP to deny all register packets.
6.3.13 Configuring BSR Policy
To prevent the valid BSRs from being maliciously replaced or BSR spoofing, BSR
policy can be configured to specify the valid BSR range. Information from BSRs out of
this range will not be accepted.
Perform the following configuration in PIM view.
Table 6-15 Configuring BSR policy
Operation Command
Configure BSR policy
bsr-policy acl-number
Remove BSR policy
undo bsr-policy
For the details of the bsr-policy command, refer to the Command Manual.
