CN4093 Application Guide for N/OS 8.2
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:
CN4093(config)# interface ip <Interface number>
CN4093(config­ip­if)# ip pim cbsr­preference <0 to 255>
CN4093(config­ip­if)# 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.
If using ACLs or VMAPs, be sure to permit traffic for local hosts and routers.
If using IGMP (see "Internet Group Management Protocol" on page
IGMP static joins can be configured with a PIM‐SM or PIM‐DM multicast group

IPv4 address. Using the ISCLI:
CN4093(config)# ip mroute <multicast group IPv4 address> <VLAN> <port>
 IGMP Query is disabled by default. If IGMP Querier is needed with PIM, be sure
to enable the IGMP Query feature globally, as well as on each VLAN where it is
needed.
If the switch is connected to multicast receivers and/or hosts, be sure to enable

IGMP snooping globally, as well as on each VLAN where PIM receivers are
attached.
