A network engineer runs the following command to troubleshoot an MPLS L3VPN issue:
R1# show bgp neighbors 10.0.0.2 received-routes
Output: BGP table version is 10, local router ID is 10.0.0.1 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S stale, m multipath, b backup-path, f RT-Filter, x best-external, a additional-path, c RIB-compressed, Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path *> 10.3.3.0/24 10.0.0.2 0 100 0 65000 i *> 10.4.4.0/24 10.0.0.2 0 100 0 65000 i
Total number of prefixes 2
What does this output indicate?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
R1 is receiving two routes from BGP neighbor 10.0.0.2
The show bgp neighbors received-routes command displays routes received from the specified neighbor. Here, R1 has received two prefixes (10.3.3.0/24 and 10.4.4.0/24) from neighbor 10.0.0.2, with next hop 10.0.0.2 and AS path 65000. These are valid and best.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
R1 is receiving two routes from BGP neighbor 10.0.0.2
Why this is correct
The `received-routes` keyword displays prefixes accepted from the neighbour before inbound policy filtering, so the two entries confirm R1 is receiving both 10.3.3.0/24 and 10.4.4.0/24 from 10.0.0.2. This satisfies the stem's requirement to verify inbound advertisements on the MPLS L3VPN session.
- ✗
R1 is advertising two routes to BGP neighbor 10.0.0.2
Why it's wrong here
The received-routes keyword displays prefixes inbound from neighbour 10.0.0.2, not prefixes R1 sends to it. The direction is tempting because the same table format appears for advertised-routes, but that command would show R1's outbound advertisements instead.
- ✗
R1 has no BGP routes
Why it's wrong here
The table lists two prefixes marked valid and best, so routes are present. Confusion arises because received-routes shows only what the neighbour sent, not whether those paths were installed in the RIB, but the output plainly displays two accepted entries.
- ✗
R1 is using OSPF to learn these prefixes
Why it's wrong here
The path column shows AS 65000 with origin code i, indicating prefixes learned via BGP from neighbour 10.0.0.2, not OSPF. OSPF-learned routes would not appear in a BGP neighbour table at all, so the protocol attribution is wrong.
