A network engineer runs the following command to troubleshoot an EIGRP issue:
R1# show ip eigrp neighbors detail
IP-EIGRP neighbors for process 100 H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 10.1.2.2 Gi0/0 13 00:12:34 12 200 0 145 Version 12.4/1.2, Retrans: 0, Retries: 0, Prefixes: 5 Topology-ids from peer - 0 Stub Peer Advertising (CONNECTED STATIC) Routes Suppressing queries
What does this output indicate?
⚠ Common exam trap
Cisco often tests the distinction between a normal EIGRP peer and a stub peer by hiding the 'Suppressing queries' line in the output, leading candidates to overlook the stub behavior and incorrectly assume the peer is a normal router forwarding all routes.
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 neighbor is a stub router that only advertises connected and static routes, and it does not participate in query propagation.
The output shows 'Stub Peer Advertising (CONNECTED STATIC) Routes' and 'Suppressing queries', which indicates the neighbor is configured as an EIGRP stub router. A stub router advertises only connected and static routes (as specified) and does not participate in query propagation, meaning it will not forward queries from other routers, reducing the query domain and improving convergence.
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 neighbor is a stub router that only advertises connected and static routes, and it does not participate in query propagation.
Why this is correct
The output shows 'Stub Peer Advertising (CONNECTED STATIC) Routes' and 'Suppressing queries', confirming stub behavior.
- ✗
The neighbor is a normal EIGRP peer that forwards all routes and queries.
Why it's wrong here
The stub designation indicates limited functionality.
- ✗
The neighbor is not forming an adjacency due to a version mismatch.
Why it's wrong here
The version numbers (12.4/1.2) are compatible, and the adjacency is up.
- ✗
The neighbor is using a different autonomous system number.
Why it's wrong here
The process number is 100, and the adjacency is established, so AS numbers match.
Quick reference
Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
