Which two measures mitigate frequent label-binding exchanges caused by a flapping link between MPLS routers? (Choose two.)

Link dampening prevents a flapping link from repeatedly withdrawing and re-advertising its routes, which would trigger excessive label-binding updates in MPLS. By suppressing unstable links for a period, it reduces the frequency of these updates. Targeted hellos, specifically for LDP (Label Distribution Protocol) sessions, establish a direct, unicast hello exchange between two LDP peers. This allows the peers to maintain their LDP session and associated label bindings even if the underlying IGP (Interior Gateway Protocol) adjacency flaps, thus preventing unnecessary label-binding exchanges. Increasing input queue, hold-timer, or session delay are not standard or effective mechanisms for mitigating frequent label-binding exchanges due to link flapping in MPLS.
