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.
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:

register-policy acl-number
Required
By default, the switch does not filter
the registration packets from DR.
Only the registration packets matching the permit command of ACLs can be accepted. When an invalid
ACL is defined, RP will reject all the registration packets.
Disabling RPT-to-SPT Switchover
Initially, a PIM-SM-enabled multicast device forwards multicast packets through an RPT. By default, the
last-hop switch initiates an RPT-to-SPT switchover process. You can also disable RPT-to-SPT
switchover through the configuration.
Follow these steps to disable RPT-to-SPT switchover:

Optional
By default, the device switches to the
SPT immediately after it receives the
first multicast packet from the RPT.
