IP reachability issue

Hello, 

in this post, I would like to share you a case about IP reachability issue due to the misconfiguration.


Problem Description

CE-03-----------U2000---------Router----------CE-04

from CE-03 both the IPs 10.10.10.66 and 10.10.10.67 are reachable 

10.10.10.66 old U2000 IP

10.10.10.67 new U2000 IP

but from CE-04 only 10.10.10.66 is reachable

 

Problem Analysis

Ask customer to explain the issue in details and feedback network topology and device diagnose information.

Check the route and find the 2 IPs have no difference.


Root Cause

It is configuration issue and device does not configure gateway.


Solution Description

Check the two different switch, the left one is connecting directly with U2000 while the right one goes to U2000 by L3. After configuring the gateway on device, it is working.


That's all for this post. 

If you have any suggestions, please comment below.

Thanks.

To deploy mobile certificate on the Agile Controller-Campus system, import the root certificate of the enterprise to the Agile Controller-Campus system and import the CRL or configure the Agile Controller-Campus system to automatically obtain the CRL periodically. When users use their own certificates to connect to the network, the Agile Controller-Campus system verifies validity of the certificates using the root certificate. If the Agile Controller-Campus system reads the CRL and detects that a user's certificate has been revoked, it does not allow the user to connect to the network.

they should be at same network at first sight, but we need detailed network configuration to analyze, in this case, it's because of one host didn't configure a gateway.
