Hello,

can you post the running config (sh run) of the 7609 ? In the meantime, check the troubleshooting info linked below:

https://www.cisco.com/c/en/us/support/docs/routers/7500-series-routers/41160-highcpu-ip-input.html

Here you have the info

Thanks in advance.

this meaning the traffic is switching use SW not HW, 
point to check 
1- are you have any issue with MTU 
2- are you config GW for client and did you disable proxy arp 

Thanks for your comments,

1. As far as I know we do not have issues with MTU, ¿is there a way to tshoot this?

2. We did not config GW for client.

Do you need another info?

 

Thanks in advance.

""As far as I know we do not have issues with MTU, ¿is there a way to tshoot this?""
I make double check you config GRE tunnel but you dont config MTU under tunnel, config MTU under tunnel 

 ""We did not config GW for client""
so the Client send arp ask IP each time it need to connect to outside it subnet, 
OK check show arp 
see if there is large number of incomplete ARP 

Ok, let me check the show arp. On the other hand we shut down bgp session and CPU utilization decreased a little bit. We are facing intermittences of LDP on the interface gi1/26, we disable LDP temporarily but CPU utiization reamins the same. 

I attach info about the interface :

interface GigabitEthernet1/26
description BB:RMMTY1_A_RAMTY3
mtu 9000
ip address 189.206.235.57 255.255.255.252
no ip redirects
ip ospf authentication message-digest
ip ospf message-digest-key 100 md5 <removed>
ip ospf network point-to-point
ip ospf cost 75
logging event link-status
load-interval 30
speed 1000
duplex full
mpls ip
mpls label protocol ldp

 

Thanks in advance.

let me check my note 

do you have any comment?

We have a large number of incomplete ARP indeed

just to mention that I dont forget you issue I analysis it, Hope tonight get something. 
for command you ask there is debug BUT with this high CPU using debug can kill your router so I will analysis data you share and figure out the issue and how can we solve it. 

Thanks a lot for your comments.

I'll be pending

I spent two nights figure out Why there is ARP for IP's include range of same subnet, 
I found that 
1- you under ping sweep miscellaneous
2- your admin run ARP-Scan to detect conflict IP

but compare to IP Input the main issue is IP Input not ARP Input.
220 1973557112 3640113288 0 5.27% 5.40% 5.42% 0 IP Input
12 644210716 793653526 811 0.71% 0.68% 0.65% 0 ARP Input

Now the issue will divide 
MTU Issue 
I see the config and see GRE multipoint tunnel meaning not P2P but multi tunnel with not set MTU this can make CPU fragment each packet sent via tunnel 

the command to check this is issue of CPU utilize 
1- do show ip traffic 
check the fragment counter 
lklklklklklkl.png
2- repeat command multi times check the fragment counter is increase rapidly or not 

if yes then you need to reduce the MTU, just to remember the MTU of GRE header is 24 bytes. 

share the show ip traffic counter here

I attach a txt with the values of MTU on the interfaces, not sure the value that I must be set on the interfaces.

Thanks in advance.
