If I enable sparse-mode on the loopback then I can ping. How would I resolve
this if I could not enable PIM on the loopback?

r3(config-if)#int lo0

r3(config-if)#ip pim sparse-mode
r3(config-if)#
*Jan 16 13:01:22.665: %PIM-5-DRCHG: DR change from neighbor 0.0.0.0 to
3.3.3.3 on interface Loopback0do ping 224.32.32.32

Type escape sequence to abort.
