Creating Multicast Boundaries and Domains
A PIM domain is a contiguous set of routers that all implement PIM and are congured to operate within a common boundary dened by
PIM multicast border routers (PMBRs).
PMBRs connect each PIM domain to the rest of the Internet.
Create multicast boundaries and domains by ltering 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.
