What/Why I did: Initially I made the change that Fallback Route [routes from AH on Upstream LC] not to get programmed [mark them as deny] on Downstream LC's as reasoning was that on Downstream LC's can forward them based on Default-route. However that assumption is correct for example we have topology like this: RH is connected to ASIC0 of Upstream LC AH is connected to ASIC1 of Upstream LC Downstream LC will learn route from RH [including default-route] and will only forward to ASIC0 of upstream LC . Above assumption was fine if we always have AH and RH connected to same ASIC of Upstream LC. How I verify: UT updated Manual Verification.
