350-401 Practice Question: Runs the following command on Router R5: R5# show…
A network engineer runs the following command on Router R5:
R5# show ip ospf border-routers
OSPF Process 1 internal Routing Table
Codes: i - Intra-area route, I - Inter-area route
i 1.1.1.1 [110/10] via 192.168.1.1, GigabitEthernet0/0, ABR, Area 0, SPF 5 i 2.2.2.2 [110/20] via 192.168.1.2, GigabitEthernet0/0, ASBR, Area 0, SPF 5
Based on this output, what can be concluded?
⚠ Common exam trap
Cisco often tests the distinction between ABR and ASBR roles in the 'show ip ospf border-routers' output, where candidates mistakenly assume any border router is an ABR or confuse the 'i' and 'I' route codes.
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 1.1.1.1 connects area 0 to another OSPF area.
The output shows an entry for 1.1.1.1 with the label 'ABR' (Area Border Router) and a route type of 'i' (intra-area). An ABR connects two or more OSPF areas, so Router 1.1.1.1 must be connecting Area 0 to another OSPF area. The metric [110/10] and next-hop 192.168.1.1 confirm it is reachable within Area 0.
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 1.1.1.1 connects area 0 to another OSPF area.
Why this is correct
ABR indicates it connects multiple areas.
- ✗
Router 2.2.2.2 is an Area Border Router.
Why it's wrong here
It is labeled ASBR, not ABR.
- ✗
Router 1.1.1.1 is redistributing external routes into OSPF.
Why it's wrong here
ASBR does that; ABR connects areas.
- ✗
The route to 2.2.2.2 is an inter-area route.
Why it's wrong here
It is marked 'i' for intra-area.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
