BSR Candidate Summary Use this page to display information about the configured BSR candidates. To display this page, click IPv4 Multicast > PIM > BSR Candidate Summary or IPv6 Multicast > PIM > BSR Candidate Summary. Figure 12-45. BSR Candidate Summary The BSR Candidate Summary page contains the following fields: • BSR Address - Displays the IP address of the elected bootstrap router (BSR). • BSR Priority - Displays the priority value of the elected BSR. • BSR Hash Mask Length - Displays the mask length of the elected BSR. • BSR Expiry Time - Time (in hours, minutes, and seconds) in which the learned elected BootStrap Router (BSR) expires. Viewing the BSR Candidate Summary using the CLI Commands For information about the CLI commands that perform this function, see the following chapter in the CLI Reference Guide: • PIM Commands Protocol Independent Multicast-Sparse Mode Protocol Independent Multicast-Sparse Mode (PIM-SM) is used to efficiently route multicast traffic to multicast groups that may span wide area networks and where bandwidth is a constraint. PIM-SM uses shared trees by default and implements source-based trees for efficiency. This data threshold rate is used to toggle between trees. PIM-SM assumes that no hosts want the multicast traffic unless they specifically ask for it. It creates a shared distribution tree centered on a defined rendezvous point (RP) from which source traffic is relayed to the receivers. Senders first send the multicast data to the RP, which in turn 714 Configuring IP Multicast
