+ | The hold up time and hold down time can be used to prevent routing loops and to improve the stability of the network. For example, if a router has a hold up time of 10 seconds and a hold down time of 20 seconds, and it declares a neighbor down, it will wait 10 seconds for a hello packet from the neighbor before declaring the neighbor down. If the router does not receive a hello packet from the neighbor within 10 seconds, it will wait 20 seconds before trying to re-establish the neighbor adjacency. This helps to prevent routing loops from occurring if the neighbor is only temporarily unavailable. | ||
+ | |||
+ | 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. | ||
