Multicast PIM Bootstrap (BSR)

The first line is R2 and the remaining lines are R1.
Should all be R2

R2(config)#interface Loopback 0
R1(config-if)#ip address 2.2.2.2 255.255.255.255
R1(config-if)#ip pim sparse-mode

R1(config)#router ospf 1
R1(config-router)#network 2.2.2.2 0.0.0.0 area 0

Now we can use the BSR command:

R1(config)#ip pim bsr-candidate loopback 0 ?
