3Com Switch 8800 Configuration Guide

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.

Refer to 28.2.5 Configuring the Filtering of Multicast Source/Group.

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.

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

Configure RP to filter the register messages

Cancel the configured filter of messages

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.

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.
