I have a Raspberry PI3 device that I am testing Observium CE on before buying the subscription version.  However, I added a cisco device that supports VRFs and the page shows 5 but it is blank.  I have an Observium CE 0.16.10.8128 running
 on a turnkey appliance and that is running fine….though the OS is Debian 8.4.  The BGP page loads fine.  Haven’t seen any other issues as of yet.
Raspberry PI install info:
