OSPF Monitoring

Hello,

I'm searching for a software which is able to visualize and monitor my OSPF setup.

I would like to have a display in my office where I can see the currently used routes to our subsidiaries. 

Google brought some answers for Cisco, SNMP and Syslog monitoring but nothing with a nice visualization.

Do you guys have something like this already in your environment or isn't this even possible with the FortiGate's.

Thanks in advance

Best regards,
