Match each component or prefix notation from a Cisco IOS routing table output to its correct technical characteristic or forwarding behavior.
- Code prefix 'D EX' in: D EX 192.168.50.0/24 [170/2578560] via 10.1.1.2Identifies an external EIGRP learned route assigned a default Administrative Distance of 170
- Bracketed notation '[110/65]' in: O 10.1.4.0/24 [110/65] via 10.1.12.1Defines the Administrative Distance of 110 followed by the OSPF path metric cost of 65
- Prefix '192.168.10.0/28' vs '192.168.10.0/24' when forwarding to 192.168.10.14Selected for traffic forwarding regardless of Administrative Distance due to Longest Prefix Match rules
- Code prefix 'C' in: C 172.16.1.0/24 is directly connected, GigabitEthernet0/0Indicates a directly connected subnet configured on an operational interface with an Administrative Distance of 0
Answer
Each routing table notation matches its corresponding definition based on Cisco IOS routing table syntax and path determination rules: 'D EX' matches external EIGRP with AD 170, '[110/65]' matches AD 110 and metric 65, the '/28' prefix matches the Longest Prefix Match rule, and 'C' matches a directly connected network with AD 0.
Each routing table component directly corresponds to Cisco IOS routing table syntax and path determination logic. 'D EX' signifies EIGRP external routes (AD 170); bracketed numbers '[110/65]' display Administrative Distance followed by Metric; destination matching favors the longest subnet mask (/28 over /24); and 'C' represents directly connected routes with an AD of 0.
