II. Configuring a PIM-SM domain border
As the administrative core of a PIM-SM domain, the BSR sends the collected RP-Set
information in the form of bootstrap messages to all routers in the PIM-SM domain.
A PIM domain border is a bootstrap message boundary. Each BSR has its specific
service scope. A number of PIM domain border interfaces partition a network into
different PIM-SM domains. Bootstrap messages cannot cross a domain border in either
direction.
Perform the following configuration on routers that can become a PIM-SM domain
border.
Follow these steps to configure a PIM-SM domain border:
To do...
Enter system view
Enter interface view
Configure a PIM-SM
domain border
Caution:
After this feature is configured, Bootstrap messages cannot pass the border. However,
the other PIM messages can pass the domain border. The network can be effectively
divided into domains that use different BSRs.

4.3.4 Filtering the Registration Packets from DR to RP

Within a PIM-SM domain, the source-side DR sends register messages to the RP, and
these register messages have different multicast source or group addresses. You can
configure a filtering rule to filter register messages so that the RP can serve specific
multicast groups. If an (S, G) entry is denied by the filtering rule, or the action for this
entry is not defined in the filtering rule, the RP will send a register-stop message to the
DR to stop the registration process for the multicast data..
Follow these steps to filter the registration packets from RP to DR:
Enter system view
Enter PIM view
Use the command...
system-view
interface interface-type
interface-number
pim bsr-boundary
To do... Use the command...
