Is there any guide for leaking routes learnt from OSPF on VRF A to VRF B?
You can try two OSPF instances and redistribute routes from one instance to another.
A simple config example would be really helpful.
??? no guide or example?
You’ve been given the idea, use documentation to go have a go yourself. If you’d like someone to consult for you reach out to some consulting businesses so they can provide config for you to use.
