Match each Cisco IOS IPv4 routing table entry component to its correct functional definition or metric descriptor.
- Administrative Distance (AD)Measures the trustworthiness of a routing protocol or route source when choosing between multiple protocols.
- Routing MetricRepresents the path cost or tie-breaker calculated by a specific routing protocol to reach a destination.
- Next-Hop AddressSpecifies the IPv4 address of the adjacent router interface where packets for the route are forwarded.
- Prefix LengthIndicates the subnet mask specifier (in CIDR notation) used to determine the most specific route match.
Answer
Administrative Distance matches the measure of route source trustworthiness; Routing Metric matches the path cost calculated by a specific protocol; Next-Hop Address matches the IPv4 address of the adjacent router interface; Prefix Length matches the subnet mask specifier in CIDR notation used for longest prefix match.
Each entry component in a Cisco IOS routing table plays a distinct role: Administrative Distance measures source believability (0-255), Routing Metric determines the best path within a specific routing protocol, the Next-Hop Address defines the adjacent router's interface IP for forwarding, and the Prefix Length dictates how many bits match the destination address during lookup.
