Create Multicast Boundaries and Domains
A PIM domain is a contiguous set of routers that all implement PIM and are configured to operate within a
common boundary defined by PIM Multicast Border Routers (PMBRs). PMBRs connect each PIM
domain to the rest of the internet.
Create multicast boundaries and domains by filtering inbound and outbound Bootstrap Router (BSR)
messages per interface, use the
ip pim bsr-border command. This command is applied to the subsequent
inbound and outbound updates. Already existing BSR advertisements are removed by timeout.
Remove candidate RP advertisements using the
clear ip pim rp-mapping command.
Configure a Dynamic RP
The rendezvous point in PIM can be configured dynamically by using BSR protocol
