A network engineer runs the following command to troubleshoot an Administrative Distance issue:

R1# show ip route 172.16.0.0 255.255.0.0

Routing entry for 172.16.0.0/16 Known via "ospf 1", distance 110, metric 20, type intra area Last update from 10.1.1.2 on GigabitEthernet0/0, 00:00:05 ago Routing Descriptor Blocks:

* 10.1.1.2, from 2.2.2.2, 00:00:05 ago, via GigabitEthernet0/0

Route metric is 20, traffic share count is 1

What does this output indicate?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The route is an OSPF intra-area route with administrative distance 110, which is the default for OSPF.

The output shows an OSPF intra-area route with administrative distance 110, which is the default for OSPF. The metric is 20, and the route is learned from neighbor 2.2.2.2.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The route is an OSPF intra-area route with administrative distance 110, which is the default for OSPF.

    Why this is correct

    OSPF routes have a default AD of 110.

  • The route is an OSPF external route with administrative distance 110.

    Why it's wrong here

    The output says 'type intra area', not external.

  • The route has an administrative distance of 20 because it is an OSPF route.

    Why it's wrong here

    The AD is 110, not 20; the metric is 20.

  • The route is preferred over an EIGRP route with AD 90.

    Why it's wrong here

    EIGRP internal AD 90 is lower than OSPF's 110, so OSPF would not be preferred.

Visual reference

R1 R2 R3 R4 10 100 10 100 OSPF picks R1→R2→R4 (cost 20) over R1→R3→R4 (cost 200)

RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
