A PIM domain is a contiguous set of routers that all implement PIM and are configured to operate within

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. The following command is applied to the subsequent inbound and outbound
updates. Timeout removes existing BSR advertisements.
