[j-nsp] Multicast flow with "Wrong incoming interface notifications" counter incrementing

[Riccardo S]

Hi

What does means incrementing counter
“Wrong incoming interface notifications” in the following command ?

Is the following flow forwarded, as expected,
towards the receiver ?

 

 

# run show multicast route group
224.12.22.1 extensive    

Instance: master Family: INET

 

Group: 224.12.22.1

   
Source: 1.1.1.1/32 

   
Upstream interface: vlan.1

   
Downstream interface list: 

        vlan.100

   
Session description: Unknown

   
Statistics: 3 kBps, 30 pps, 43340 packets

   
Next-hop ID: 131071

   
Upstream protocol: PIM

   
Route state: Active

   
Forwarding state: Forwarding

   
Cache lifetime/timeout: 360 seconds

   
Wrong incoming interface notifications: 6960

   
Uptime: 00:36:36

 

After 10 seconds:

 

# run show multicast route group
224.12.22.1 extensive    

Instance: master Family: INET

 

Group: 224.12.22.1

   
Source: 1.1.1.1/32 

   
Upstream interface: vlan.1

   
Downstream interface list: 

        vlan.100
