PIM Configuration Examples
Example 1: PIM-SM with Dynamic RP
This example configures PIM Sparse Mode for one IP interface, with the switch acting as a
candidate for dynamic Rendezvous Point (RP) selection.
1. Globally enable the PIM feature:
2. Configure a PIM network component with dynamic RP settings, and set it for PIM Sparse Mode:
Where 225.1.0.0 is the multicast group base IP address, 255.255.0.0 is the multicast group address
mask, and 10.10.1.1 is the switch RP candidate address.
Note – Because, Sparse Mode is set by default for PIM component 1, the mode command is
needed only if the mode has been previously changed.
3. Define an IP interface for use with PIM:
The IP interface represents the PIM network being connected to the switch. The IPv4 addresses in
the defined range must not be included in another IP interface on the switch under a different
VLAN.
4. Enable PIM on the IP interface and assign the PIM component:
Note – Because, PIM component 1 is assigned to the interface by default, the component-id
command is needed only if the setting has been previously changed.
5. Set the Bootstrap Router (BSR) preference:
RS G8124(config)# ip pim enable
RS G8124(config)# ip pim component 1
RS G8124(config-ip-pim-comp)# mode sparse
RS G8124(config-ip-pim-comp)# rp-candidate rp-address 225.1.0.0
255.255.0.0 10.10.1.1
RS G8124(config-ip-pim-comp)# exit
RS G8124(config)# interface ip 111
RS G8124(config-ip-if)# ip address 10.10.1.1 255.255.255.255
RS G8124(config-ip-if)# vlan 11
RS G8124(config-ip-if)# enable
RS G8124(config-ip-if)# ip pim enable
RS G8124(config-ip-if)# ip pim component-id 1
RS G8124(config-ip-if)# ip pim cbsr-preference 135
RS G8124(config-ip-if)# exit
