A network administrator is inspecting an IPv4 routing table on a Cisco router to understand how paths to remote networks are chosen. Match each routing table component on the left with its corresponding function or definition on the right.
- Administrative Distance (AD)Quantifies the trustworthiness of a route source, where a lower value indicates a more believable source.
- Routing MetricRepresents the path cost computed by a routing protocol to select the best route among paths from the same protocol.
- Next-Hop IP AddressIdentifies the immediate adjacent router interface to which packets destined for the network should be forwarded.
- Destination Prefix and Subnet MaskDefines the specific target network address range and boundary against which incoming packet destination IP addresses are matched.
Cevap
Administrative Distance matches trustworthiness of the route source; Routing Metric matches path cost calculated by a specific protocol; Next-Hop IP Address matches the immediate adjacent router interface address; Destination Prefix and Subnet Mask matches the target network range against which traffic is matched.
Each routing table component serves a distinct role in packet forwarding decisions: Administrative Distance rates protocol trustworthiness, Routing Metric measures path cost for a single protocol, Next-Hop IP specifies the adjacent forwarding device, and Destination Prefix/Mask defines the destination network range.
