A network engineer runs the following command to troubleshoot a Control Plane Policing (CoPP) issue:
R1# show bgp neighbors 10.1.1.2 advertised-routes
BGP table version is 10, local router ID is 10.1.1.1 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 *> 10.2.2.0/24 0.0.0.0 0 32768 i
Total number of prefixes 1
What does this output indicate?
⚠ Common exam trap
Watch out — candidates often assume CoPP can affect outbound BGP updates, but CoPP only polices inbound control plane traffic, so a successful advertised-routes output proves CoPP is not the cause of any advertisement failure.
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
✓
BGP is advertising routes correctly, and CoPP is not affecting outbound updates.
The output shows that BGP has one prefix (10.2.2.0/24) in the advertised-routes table for neighbor 10.1.1.2, with the next hop set to 0.0.0.0 (indicating a locally originated route). This confirms that BGP is successfully advertising routes outbound, and there is no evidence of CoPP dropping update packets. CoPP would only affect control plane traffic destined to the router itself, not outbound BGP updates, which are forwarded in the data plane.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
BGP is not advertising routes due to CoPP dropping update packets.
Why it's wrong here
One route is being advertised, so updates are being sent.
- ✓
BGP is advertising routes correctly, and CoPP is not affecting outbound updates.
Why this is correct
The route is advertised with weight 32768, indicating local origin, and no errors are shown.
- ✗
BGP is receiving routes but not advertising them due to CoPP.
Why it's wrong here
The output shows advertised routes, not received.
- ✗
BGP session is down due to CoPP.
Why it's wrong here
The output is valid, indicating the session is up.
