sh ip mroute count - not forwarding multicast ?

Router1#sh ip mroute count

Group: 224.200.1.2, Source count: 2, Packets forwarded: 0, Packets received: 66

  Source: 192.168.32.60/32, Forwarding: 0/0/0/0, Other: 30/28/2

  Source: 192.168.32.61/32, Forwarding: 0/0/0/0, Other: 36/34/2

All (follow up to my initial question earlier). Does forwarding 0/0/0/0 imply that this switch is not forwarding my data? If so? Why would my switch do this? What needs to be changed?

From what I see, the data is coming in but not being forwarded - is this true?

Thank you in advance,

Ashley

Hello, could you please confirm if this is a layer 2 & layer 3 switch? Which pim mode is being used? Is RP available if required? Igmp enabled?

Hi Ashley,

Router1#sh ip mroute count

Group: 224.200.1.2, Source count: 2, Packets forwarded: 0, Packets received: 66

  Source: 192.168.32.60/32, Forwarding: 0/0/0/0, Other: 30/28/2

  Source: 192.168.32.61/32, Forwarding: 0/0/0/0, Other: 36/34/2

From this output we can see that packets for (192.168.32.60,224.200.1.2) are getting dropped, and specifically the reason they are getting dropped is because of RPF failure.  This is seen from the “Other: 30/28/2” output, where the second field is RPF failed drops. For more detail let’s look at the packet trace.

Kindly check the RPF path,IGMP enabling,o rstatically adding the ip mroute command for that particular destination.

HTH
