Hi,
We are facing strange issue in our network. We have a remote branch which is connected to main branch using Leased Line. Remote branch is having Cisco 1700 Router. Every day in the morning time the remote router is unreachable. We are not able to reach (ping/telnet) the remote Router but able to reach L3 switch/ LAN behind this router. The users from remote branch is also not able to reach the local router but they are able to ping the Main branch.
Users in the remote branch are not able to access any resources in the main branch during the issue.
During the issue, we have checked the remote branch router and found the CPU utilization of the Cisco 1700 router is very high (99%). If we run "Show process CPU" command (please find the attachment) specially IP input process is very high (97%).
Please guide us to troubleshoot this issue.
Thanks,
som
