3Com Switch 8800 Configuration Guide Chapter 29 PIM-SM Configuration
29-7
By default, no domain border is set. After this configuration is performed, a bootstrap
message can not cross the border but other PIM packets can. This configuration can
effectively divide a network into domains using different BSRs.
29.2.9 Configuring the filtering of multicast source/group Refer to 28.2.5 Configuring the Filtering of Multicast Source/Group.
29.2.10 Configuring the filtering of PIM neighbor Refer to 28.2.6 Configuring the Filtering of PIM Neighbor.
Refer to 28.2.7 Configuring the Maximum Number of PIM Neighbor on an Interface.
29.2.11 Configuring RP to Filter the Register Messages Sent by DR In the PIM-SM network, the register message filtering mechanism can control which
sources to send messages to which groups on the RP, i.e., RP can filter the register
messages sent by DR to accept specified messages only.
Perform the following configuration in PIM view.
Table 29-6 Configuring RP to filter the register messages sent by DR
Operation Command
Configure RP to filter the register messages
sent by DR register-policy acl-number
Cancel the configured filter of messages undo register-policy
If an entry of a source group is denied by the ACL, or the ACL does not define operation
to it, or there is no ACL defined, the RP will send RegisterStop messages to the DR to
prevent the register process of the multicast data stream.
Caution:
Only the register messages matching the ACL permit clause can be accepted by the
RP. Specifying an undefined ACL will make the RP deny all register messages.
To prevent the legal BSR from being replaced maliciously in the network, you can limit
the range of legal BSR. Other BSR messages beyond the range are not received by the
router and thus ensure the BSR security.
