Re: [c-nsp] Forcing BGP to propagate only after route is in the FIB

Do you folks experience this only in scenarios without backup please? My understanding is that this should not be happening if the prefixes are maintained in the FIB by means of switching from backup NH back to primary NH But I recognize it is a problem even with a single NH I'm thinking if the
