A device receives a route update for network 172.19.0.0/16 from two different routing information sources. In this scenario, which parameter will determine the active route?
In routing protocols, when a device receives multiple advertisements for the same network from different sources, the route with the lowest default route preference (also known as administrative distance) is selected as the active route. Each routing protocol has a default preference value, and the device uses these values to determine which route to prefer when multiple routes are available for the same destination.
n Junos OS, when a device receives a route update for the same network (in this case, 172.19.0.0/16) from multiple routing information sources, the active route will be determined based on the route preference or administrative distance. Each routing protocol has a default preference value associated with it, and the route with the lowest preference value will be selected as the active route. Therefore, the correct answer is A. The route learned with the lowest default route preference will determine the active route.
