 The hold up time and hold down time can also be used to improve the stability of the network by preventing flapping. Flapping occurs when a routing loop is created and then broken, and then created again. This can happen if a router is constantly declaring neighbors down and then up again. The hold up time and hold down time can help to prevent flapping by preventing a router from declaring a neighbor down too quickly. The hold up time and hold down time can also be used to improve the stability of the network by preventing flapping.
