Fast down detection or sub-second link failure detection is needed in a modern networks. Network operators of modern networks require that they can detect failure in sub-second and react to either soft or hard failures as quickly as possible. The following are the two categories of fast down detection. 1. Polling One of the method…

EIGRP Metric
EIGRP uses the following equation in computing its metric. EIGRP metric = [K1 * bandwidth + (K2 * bandwidth)/256 – load) + K3 * delay]*[K5/(reliability + K4)] By default, EIGRP’s K values are set to: K1 and K3 = 1 K2, K4 and K5 = 0 Substituting K values yields to this condense equation. EIGRP…
