300-410 Practice Question: Runs the following command to verify MPLS L3VPN…
A network engineer runs the following command to verify MPLS L3VPN operation:
R1# show bgp ipv4 unicast 10.1.1.0/24
Output: BGP routing table entry for 10.1.1.0/24, version 10 Paths: (1 available, best #1, table default) 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
What does this output indicate?
⚠ Common exam trap
The trap is misreading '0.0.0.0 from 0.0.0.0' as a missing or invalid peer — candidates unfamiliar with BGP output may think the route is broken, when in fact it is the standard signature of a locally originated route.

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 is the best path
The output shows 'Local' origin, '0.0.0.0 from 0.0.0.0', 'weight 32768', and 'sourced, best', which are all indicators that the route was locally originated on this router (e.g., via a network statement or redistribution) and is currently the best path. The 'best #1' and 'valid, sourced, best' confirm it is selected for the BGP table. There is no peer address or AS path, which rules out learning from a BGP neighbor.
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 locally originated and is the best path
Why this is correct
The 'Local' origin with weight 32768, valid, sourced and best flags shows the prefix was injected on this router rather than learned from a peer, and BGP selected it as the active path. This confirms local origination and best-path selection.
- ✗
The route is learned from a BGP peer
Why it's wrong here
The path shows "Local" with next hop 0.0.0.0 and weight 32768, meaning R1 originated the prefix itself; a peer-learned route would list the neighbour's IP as the from address. It is tempting because BGP tables routinely hold peer-learned entries, but this specific output describes a locally sourced route.
- ✗
The route has an MPLS label
Why it's wrong here
No label stack, RD, or VPNv4 NLRI appears; the entry is plain IPv4 unicast in the default table, so no MPLS label is associated. It is tempting because the stem concerns MPLS L3VPN, where labelled VPNv4 routes are expected, but this command displays the global IPv4 table instead.
- ✗
The route is in a VRF
Why it's wrong here
The header states "table default", so the route sits in the global BGP table, not a VRF; VRF routes appear under a named table. It is tempting because L3VPN verification often involves VRF tables, and the command's unicast keyword resembles per-VRF lookups, but no RD or VPNv4 context is present here.

LDP Protocol
LDP, or Label Distribution Protocol, is a protocol that routers use to automatically exchange labels that enable MPLS (Multiprotocol Label Switching) to create fast, efficient paths for data packets across a network.
Key term
MPLS Layer 3 VPN
A technology that uses Multiprotocol Label Switching to create secure, scalable virtual private networks that connect multiple sites at the network layer, where the service provider manages routing between customer sites.
