I've searched here and there and failed to find someone mentioned this - Maybe that indicates not possible.
But I still wanna have a definite answer: assuming we have 3 VRF - A, B and C.
Can we leak routes from VRF A to VRF B then leak those(or part of) routes from VRF B to VRF C and vice versa? More than just shared services inside of VRF B.
I know just for 3 VRFs, not really necessary to create such middle man, however, if we have tens of VRFs, having a transit to control route exchange among VRFs makes sense.
I can tell we should be able archive such target by only using L3out, peering L3out between VRFs - also a tedious work if too many VRFs and involving physical cabling I guess.
Please shed some light on how to solve such situation.
Thank you!
