Hello, I am having a strange problem in a multicast network, when i do "show ip mroute count" i see the following:
Group: 220.127.116.11, Source count: 1, Packets forwarded: 4215072, Packets received: 4218034
RP-tree: Forwarding: 0/0/0/0, Other: 2962/101/2861
Source: 18.104.22.168/32, Forwarding: 4215073/255/165/301, Other: 4215073/0/0
As you can see there is a diference on forwaded packets and received, but i dont have on the "Other: 4215073/0/0" any counters for RPF failed or other drops, others mcast groups are ok, so the big question is, what is happening to this packets?
Note - in cpu history i dont have any high value
I make that 2962 packets you are missing. You can see in your stats that these have been counted:
This means 101 packets were dropped due to RPF failure and 2861 packets were dropped due to other reasons (OIF-null, rate-limit etc)
To check the 2861 packets you can check to see if you have multicast rate limiting enabled and you can also check the downstream join/IGMP join to see it's uptime etc..
