Operation Manual – MulticastH3C S5600 Series Ethernet Switches Chapter 4 PIM Configuration4-16II. Configuring a PIM-SM domain borderAs the administrative core of a PIM-SM domain, the BSR sends the collected RP-Setinformation 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 specificservice scope. A number of PIM domain border interfaces partition a network intodifferent PIM-SM domains. Bootstrap messages cannot cross a domain border in eitherdirection.Perform the following configuration on routers that can become a PIM-SM domainborder.Follow these steps to configure a PIM-SM domain border:To do... Use the command...

However,the other PIM messages can pass the domain border. The network can be effectivelydivided into domains that use different BSRs.4.3.4 Filtering the Registration Packets from DR to RPWithin a PIM-SM domain, the source-side DR sends register messages to the RP, andthese register messages have different multicast source or group addresses. You canconfigure a filtering rule to filter register messages so that the RP can serve specificmulticast groups. If an (S, G) entry is denied by the filtering rule, or the action for thisentry is not defined in the filtering rule, the RP will send a register-stop message to theDR to stop the registration process for the multicast data..Follow these steps to filter the registration packets from RP to DR:To do...
