Which factor determines the best path to forward a packet when there are multiple paths available to a destination network using the same routing protocol?
|
|
Lowest metric
|
|
|
Lowest administrative distance
|
|
|
Order of the paths in the routing table
|
|
|
Priority value of protocol
|
Explanation:
Detailed explanation-1: -Whenever multiple paths to the same network exist, each path uses a different exit interface on the router to reach that network. The best path is selected by a routing protocol based on the value or metric it uses to determine the distance to reach a network.
Detailed explanation-2: -A distance-vector routing protocol in data networks determines the best route for data packets based on distance. Distance-vector routing protocols measure the distance by the number of routers a packet has to pass; one router counts as one hop.
Detailed explanation-3: -Load balancing allows a router to forward packets over multiple paths to the same destination network.
