Rene,
Based on the below entry:
"Above you can see that R2 is receiving the RP announcement traffic from R1. Let’s check R3:
R3#show ip mroute | begin 224
(*, 224.0.1.39), 00:05:28/00:01:57, RP 0.0.0.0, flags: DC
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
GigabitEthernet0/2, Forward/Sparse, 00:05:28/00:01:57
(*, 224.0.1.40), 00:27:34/stopped, RP 0.0.0.0, flags: DPL
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list: Null
(2.2.2.2, 224.0.1.40), 00:04:29/00:02:29, flags: PLT
<strong>Incoming interface: GigabitEthernet0/2</strong>, RPF nbr 192.168.23.2
Outgoing interface list: Null
"
If I am not wrong, the incoming interface should be Gi0/1, which is the interface connected towards the RP mapping agent (2.2.2.2). Gi0/2 is the interface connected to GI0/4.
Let me know if I am missing something.
Thanks,
Jose
