GRE Tunnel is not Coming UP

L0 Member

We've created eight GRE tunnels and it's working fine. But when going to create another Tunnel, the tunnel is not coming up. We've tried to changing the remote site router, but no luck.

Thank you for the post @nazrul13 

 

Could you check in System log with filter: (subtype eq gre) any corresponding logs? What is the model of the router? If it is Cisco, could you turn debugs:

 debug tunnel packet

 debug tunnel keepalive

 debug tunnel event

 

Kind Regards

Pavel
