In the following partial output of the show ip route command, what does the letter D stand for?
D 192.1.2.0/24 via 5.1.1.71 [w:0 m:0]
C 192.8.1.1/32 directly connected to loopback 0

A.
This is a default route

B.
This is an EIGRP route

C.
This is static route

D.
This is a directly connected route

Explanation:
The letter D indicates that it was a route learned by the EIGRP routing protocol. In the output of the show ip route command, each route will have a letter next to it
that indicates the method by which the route was learned. At the beginning of the output will be a legend describing the letters as shown below:
Router# show ip route
Codes: I – IGRP derived, R – RIP derived, O – OSPF derived,
C – connected, S – static, E – EGP derived, B – BGP derived,
* – candidate default route, IA – OSPF inter area route,
i – IS-IS derived, ia – IS-IS, U – per-user static route,
o – on-demandrouting, M – mobile, P – periodic downloaded static route,
D – EIGRP, EX – EIGRP external, E1 – OSPF external type 1 route,
E2 – OSPF external type 2 route, N1 – OSPF NSSA external type 1 route,
N2 – OSPF NSSA external type 2 route
The letter does not indicate that it is a default route. The default route (if configured) will appear at the end of the legend as follows:
Gateway of last resort is 10.119.254.240 to network 10.140.0.0
The letter does not indicate that it is a static route. Static routes will have an “S” next to them.
The letter does not indicate that it is a directly connected route. Directly connected routes will have a “C” next to them.
