In my network we are facing high CPU causing because of multicast traffic...
The source of mylticast having 155.x.x.x and Group 239.x.x.x.
currently we have placed a access-list to stop causing high CPU as below but now concerned is that we are not able to get the multicast video from this source.
access-list 1 deny 184.108.40.206 0.255.255.255
When we take out the above acl so again it causing the high CPU.. I have checked the and found the RPF failure as below,
ds1#sh ip mroute 239.x.x.x count
IP Multicast Statistics
102 routes using 77310 bytes of memory
29 groups, 2.51 average sources per group
Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kilobits per second
Other counts: Total/RPF failed/Other drops(OIF-null, rate-limit etc)
Group: 239.x.x.x, Source count: 1, Packets forwarded: 0, Packets received: 467885775
RP-tree: Forwarding: 0/0/0/0, Other: 0/0/0
Source: 155.x.x.x/32, Forwarding: 0/-92/0/0, Other: 467885775/20990877/446894898
Please anyone can help to find the issue and how we may resolve it?
Appreciate your time and efforts for me.
Thanks and Regards
