Creating 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. The
following command is applied to the subsequent inbound and outbound updates. Timeout removes existing BSR advertisements.
● Create multicast boundaries and domains by filtering inbound and outbound BSR messages per interface.
ip pim bsr-border
● Remove candidate RP advertisements.
clear ip pim rp-mapping
