Which value in a routing table is used to compare routes received from a routing protocol?
- administrative distance
- metric
- outgoing interface
- routing protocol
Explanation: A metric is used by a routing protocol to compare routes received from the routing protocol. An exit interface is the interface used to send a packet in the direction of the destination network. A routing protocol is used to exchange routing updates between two or more adjacent routers. The administrative distance represents the trustworthiness of a particular route. The lower an administrative distance, the more trustworthy the learned route is. When a router learns multiple routes toward the same destination, the router uses the administrative distance value to determine which route to place into the routing table.
