Hi Rene,

I setup same LAB in VIRL, the previous LAB was GNS3, right now its showing this debug message

`Aug 22 05:13:25.023: %PIM-4-INVALID_SRC_REG: Received Register from 2.2.2.2 for (12.12.12.1, 239.9.9.9), not willing to be RP`

from R2 (Which is the RP), but even though I’m receiing INVALID-Source address its still allowing to ping the group address and even setting up in multicast routing.

```
(12.12.12.1, 239.9.9.9), 00:02:26/00:00:33, flags: FT
 
 Incoming interface: GigabitEthernet0/1, RPF nbr 12.12.12.1
  Outgoing interface list:
    GigabitEthernet0/2, Forward/Sparse, 00:02:26/00:02:04

```

Regards  
Jama
