- A
The output displays only routes that are locally originated by the PE router.
Why wrong: Incorrect. The output shows all VPNv4 routes in the BGP table for that VRF, including routes learned from remote PEs.
- B
The output includes the Route Distinguisher (RD) for each prefix.
Correct. The RD is displayed as part of the prefix (e.g., '100:1:10.1.1.0/24').
- C
The output shows the MPLS label assigned to each route.
Correct. The label is displayed in the 'Label' column or as part of the path information.
- D
The output is equivalent to 'show ip route vrf <vrf-name>'.
Why wrong: Incorrect. 'show ip route vrf' shows the IP routing table, not the BGP table.
- E
The output provides the CEF forwarding information for each prefix.
Why wrong: Incorrect. CEF information is shown by 'show ip cef vrf <vrf-name>', not by this BGP command.
Quick Answer
The correct answer is that the output of the show ip bgp vpnv4 vrf command displays the MPLS label assigned to each route. This is because the command reveals the BGP table for a specific VRF, showing VPNv4 routes that have been imported, including the route distinguisher, next-hop, and critically, the MPLS label used for label switching across the MPLS VPN backbone. On the Cisco CCNP ENARSI 300-410 exam, this question tests your ability to distinguish between BGP VPNv4 output and other VRF verification commands; a common trap is confusing this with the full VRF routing table from show ip route vrf, which does not include labels. Remember that the BGP table always carries label information for VPNv4 prefixes, while the routing table does not. A helpful memory tip: "BGP labels the VPN, the routing table just shows the path."
300-410 MPLS L3VPN Practice Question
This 300-410 practice question tests your understanding of mpls l3vpn. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Which TWO statements about the 'show ip bgp vpnv4 vrf <vrf-name>' command output are correct? (Choose TWO.)
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 output includes the Route Distinguisher (RD) for each prefix.
The command 'show ip bgp vpnv4 vrf <vrf-name>' displays the BGP table for the specified VRF, including VPNv4 routes that have been imported. It shows the RD, the next-hop, and the route label. It does not show the full VRF routing table (which is seen with 'show ip route vrf'), nor does it show the CEF forwarding table. The output includes both locally originated and remote routes that have been accepted. The label information is present in the output.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

- ✗
The output displays only routes that are locally originated by the PE router.
Why it's wrong here
Incorrect. The output shows all VPNv4 routes in the BGP table for that VRF, including routes learned from remote PEs.

- ✗
The output is equivalent to 'show ip route vrf <vrf-name>'.
Why it's wrong here
Incorrect. 'show ip route vrf' shows the IP routing table, not the BGP table.
- ✗

Why it's wrong here
Incorrect. CEF information is shown by 'show ip cef vrf <vrf-name>', not by this BGP command.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Incorrect. The output shows all VPNv4 routes in the BGP table for that VRF, including routes learned from remote PEs.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
