Routers missing on Network

Routers missing on Network

Hi There

I have an issue where I am not able to discover/add routers into opmanager network which existed previously but deleted by mistake. how ever the same/all routers are visible in Netflow but I cant seem to add under network any ideas how to resolve the issue


I am using OPmanager 9410

I have tried rediscovery, add a device which picks up but doesn't discover any interfaces on the device

Please advise if you require more information.

Thanks
