Interface down/down on router interface

[HW05194]

Hi everyone, 

I am trying to set up an eigrp lab on EVE-NG but on one router every time I set up the interface and no shut it I get the following messages:

*Apr 26 02:14:34.500: %LINK-5-CHANGED: Interface Ethernet0/0, changed state to administratively down
R8(config-if)#
*Apr 26 02:14:37.013: %LINK-3-UPDOWN: Interface Ethernet0/0, changed state to up
*Apr 26 02:14:38.013: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0/0, changed state to up
R8(config-if)#

*Apr 26 02:14:48.017: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0/0, changed state to down

This is my configuration:

R8#show run int e0/0
Building configuration...

Current configuration : 79 bytes

Whenever I no shut the interface, I am able to ping myself for like 5 seconds then the interface goes down again. Not sure how to go about fixing this issue any help would be greatly appreciated.

Hello,

Try rebooting the device. Sometimes those virtualized instances are glitchy. If that does not work delete R8 and replace it with a new Router in the EVE-NG lab

Hope that helps

Hi David,

Thanks for getting back to me I actually already wiped the router and was experiencing the same issues, so I replaced it with a new router (same version though) and was still experiencing the same issue. I will try that again and maybe switch to a different version of the router and will let you know if that works. 

Thanks again,

Ok. If that doesn't work save configurations and restart the EVE-NG server. I don't see anything in the config that would make it shut down unless you didn't have an active link connecting that interface to another device.

Ok, perfect If it doesn't work, I will definitely try that. And yes, I do have a device connecting to this device with an active link. I should have mentioned that

Switching to a Cisco vIOS router worked for me thanks again for your help David!
