Most routing protocols can remove indirect next hops if the dependent interface has been determined to have gone down. LACP/Bonding is anotjer challenge that requires either min-links or micro BFD. BFD is often run at aggressive intervals (less than 1000ms for detecting a failure), and is not best suited for running on general purpose CPUs performing all of the management and control plane tasks. BFD is ideally implementes in hardware.
