- A
The route is locally originated and has no MPLS label
The route is sourced locally (0.0.0.0 from 0.0.0.0) and the mpls labels are nolabel/nolabel.
- B
The route is learned from a BGP peer
Why wrong: The next hop is 0.0.0.0, indicating local origin, not from a peer.
- C
The route has an MPLS label of 100
Why wrong: The extended community RT:100:100 is not an MPLS label; labels are nolabel.
- D
The route is not best
Why wrong: The output explicitly states 'best'.
Question 2,099 of 2,152
show bgp vpnv4 vrf Command in MPLS L3VPN
This 300-410 practice question tests your understanding of mpls l3vpn. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer runs the following command to troubleshoot an MPLS L3VPN issue:
R1# show bgp vpnv4 vrf CUSTOMER-A 10.1.1.0/24
Output: BGP routing table entry for 10.1.1.0/24, version 10 Paths: (1 available, best #1, table CUSTOMER-A) Advertised to update-groups: 1 Refresh Epoch 1 Local
0.0.0.0 from 0.0.0.0 (10.0.0.1)
Origin incomplete, metric 0, localpref 100, weight 32768, valid, sourced, best Extended Community: RT:100:100 mpls labels in/out nolabel/nolabel
What does this output indicate?
Quick Answer
The answer is that the route is locally originated and has no MPLS label. This is correct because the output of the **show bgp vpnv4 vrf** command for prefix 10.1.1.0/24 in VRF CUSTOMER-A shows a next hop of 0.0.0.0, which indicates the route was injected locally (e.g., via a connected network or a static route redistributed into BGP), and the "mpls labels in/out nolabel/nolabel" field confirms that no MPLS label has been assigned to this prefix. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your ability to interpret VPNv4 BGP table output and identify when a route is missing its MPLS label—a common troubleshooting point in MPLS L3VPN deployments. A frequent trap is assuming that any route in the VPNv4 table automatically has a label; however, locally originated routes often lack one unless explicitly configured with label allocation. Remember the memory tip: "Local next hop, no label drop"—if the next hop is 0.0.0.0, expect nolabel.
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 locally originated and has no MPLS label
This shows a VPNv4 route for prefix 10.1.1.0/24 in VRF CUSTOMER-A. The path is local (sourced from this router), with next hop 0.0.0.0, and the route is valid and best. The extended community is RT:100:100. The mpls labels show nolabel/nolabel, meaning no MPLS label is assigned for this prefix, which could indicate a problem if labels are expected.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The route is locally originated and has no MPLS label
Why this is correct
The route is sourced locally (0.0.0.0 from 0.0.0.0) and the mpls labels are nolabel/nolabel.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The route is learned from a BGP peer
Why it's wrong here
The next hop is 0.0.0.0, indicating local origin, not from a peer.
- ✗
The route has an MPLS label of 100
Why it's wrong here
The extended community RT:100:100 is not an MPLS label; labels are nolabel.
- ✗

Why it's wrong here
The output explicitly states 'best'.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
