Does Fortigate 6.4 support RIP routing inside VRF?

Hello Radu_sec,

Currently, FortiOS does not support RIP with non-default VRFs.

There is an NFR (New Feature Request) with ID 0748519 created to add this feature in future. But, this does not guarantee that the feature will be added in future. 

Please contact your Sales Representative if you need more information regarding the NFR and want to see it in future.
