DR priority value, it overrides the IP address selection process. If more than one
interface on a domain is configured with a DR priority, the one with the highest
number is selected.
Use the following commands to configure the DR priority value (Interface IP
mode):
RS G8264(config)# interface ip <Interface number>
RS G8264(config­ip­if)# ip pim dr­priority <value (0‐4294967294)>
RS G8264(config­ip­if)# exit
Note: A value of 0 (zero) specifies that the G8264 will not act as the DR. This
setting requires the G8264 to be connected to a peer that has a DR priority setting of
1 or higher to ensure that a DR will be present in the network.
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:
RS G8264(config)# interface ip <Interface number>
RS G8264(config­ip­if)# ip pim cbsr­preference <0 to 255>
RS G8264(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 switch.
Loopback interfaces can be used in PIM Sparse Mode for Rendezvous Points (RPs)
and Bootstrap Routers (BSRs). For example:
 As a static RP
interface loopback 1
ip address 55.55.1.1 255.255.255.0
enable
exit
ip pim static­rp enable
ip pim component 1
rp­static rp­address 224.0.0.0 240.0.0.0 55.55.1.1
interface loopback 1
ip pim enable
exit
