Specifying a Bootstrap Router
© Copyright Lenovo 2017
Using PIM‐SM, a Bootstrap Router (BSR) is a PIM‐capable router that hosts the
election of the RP from available candidate routers. For each PIM‐enabled IP
interface, the administrator can set the preference level for which the local interface
becomes the BSR:
CN 4093(config)# interface ip <Interface number>
CN 4093(config-ip-if)# ip pim cbsr-preference <0 to 255>
CN 4093(config-ip-if)# exit
A value of 255 highly prefers the local interface as a BSR. A value of ‐1 indicates
that the PIM CBSR preference is not configured on the local interface.
