300-410 Practice Question: Runs the following command to troubleshoot OSPF…

A network engineer runs the following command to troubleshoot OSPF route propagation:

R1# show ip ospf database router 2.2.2.2

OSPF Router with ID (1.1.1.1) (Process ID 1)

Router Link States (Area 0)

LS age: 45 Options: (No TOS-capability, DC) LS Type: Router Links Link State ID: 2.2.2.2 Advertising Router: 2.2.2.2 LS Seq Number: 80000005 Checksum: 0x1234 Length: 48 Number of Links: 2

Link connected to: a Transit Network (Link ID) Designated Router address: 10.1.1.2 (Link Data) Router Interface address: 10.1.1.2 Number of TOS metrics: 0 TOS 0 Metrics: 10

Link connected to: a Stub Network (Link ID) Network/subnet number: 192.168.1.0 (Link Data) Network Mask: 255.255.255.0 Number of TOS metrics: 0 TOS 0 Metrics: 10

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

Router 2.2.2.2 has a link to a transit network with DR address 10.1.1.2 and a stub network 192.168.1.0/24.

The output shows the router LSA from neighbor 2.2.2.2, listing its connected links including a transit network and a stub network.

Answer analysis

Option-by-option breakdown

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

  • Router 2.2.2.2 is advertising two stub networks.

    Why it's wrong here

    One link is a transit network (to a DR), the other is a stub network.

  • Router 2.2.2.2 has a link to a transit network with DR address 10.1.1.2 and a stub network 192.168.1.0/24.

    Why this is correct

    The LSA shows exactly these two links with their types and metrics.

  • The LSA indicates a Type 5 External LSA from ASBR.

    Why it's wrong here

    This is a Type 1 Router LSA, not an external LSA.

  • The output shows the network LSA for the transit network.

    Why it's wrong here

    The LS Type is Router Links, indicating a Router LSA.

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