Hellow friend today we will know about the what is the administrative sdistance and what is the metric.
(Administrative distance)
A network can usemore one routing protocol, and routers on the network can learn about a route from multiple sources.
Router need to find a way to select a better path. Administrative distance number is used by routers to find out which route is better (lower number is better). For example, if the same route is learned from RIP and EIGRP, a Cisco router in the routing table. This is because EIGRP routes have, by default, an administrative distance of 90, while RIP route have a higher administrative distance of 120.
(Metric)
What is the matric if a router learns two different paths for the same network from the same routing protocol,it has to decide which route is better and will be placed in the routing table. Metric is a Measure used to decide which route is better ( lower number is better). Each routing protocol uses hop counts as a metric, while ospf uses cost. So this is all about the administrative distance and metric
