A network engineer runs the following command to troubleshoot a Network Logging and Syslog issue:
R1# show ip route summary
Output: Route Source Networks Subnets Overhead Memory (bytes) connected 0 2 0 0 static 0 0 0 0 ospf 1 5 10 0 0 bgp 65001 3 5 0 0
Total 8 17 0 0
What does this output indicate?
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 routing table contains 8 networks and 17 subnets, with OSPF contributing the most routes.
The output shows the routing table summary, including the number of networks and subnets from each routing protocol. This helps in understanding the routing table size and protocol contributions.
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 routing table contains 8 networks and 17 subnets, with OSPF contributing the most routes.
Why this is correct
The totals show 8 networks and 17 subnets; OSPF has 5 networks and 10 subnets.
- ✗
The router has a routing table with 25 total routes.
Why it's wrong here
The total is 8 networks and 17 subnets, not 25 routes.
- ✗
The router is using BGP as the primary routing protocol.
Why it's wrong here
OSPF has more routes than BGP.
- ✗
The router has no static routes configured.
Why it's wrong here
The output shows 0 static routes, but that does not indicate configuration status.
Visual reference
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.
