CCNP Practice Question: Given the following configuration: router eigrp…
Given the following configuration:
router eigrp TEST network 10.0.0.0 0.255.255.255 network 192.168.1.0
!
interface GigabitEthernet0/0 ip address 10.1.1.1 255.255.255.0 ip summary-address eigrp TEST 10.0.0.0 255.0.0.0 5
What is the effect of the ip summary-address command?
⚠ Common exam trap
Cisco often tests the misconception that the number after the summary address is a metric or hop count, when in fact it is the administrative distance for the summary route.

Correct answer & explanation
✓
It creates a summary route 10.0.0.0/8 with a metric of 5, advertised out GigabitEthernet0/0.
The `ip summary-address eigrp TEST 10.0.0.0 255.0.0.0 5` command creates a summary route of 10.0.0.0/8 with an administrative distance of 5, which is advertised out of GigabitEthernet0/0. The EIGRP process name TEST matches the router eigrp configuration, and the summary is generated regardless of the network statements, as long as the router has a more specific route within the summarized range.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It creates a summary route 10.0.0.0/8 with a metric of 5, advertised out GigabitEthernet0/0.
Why this is correct
The summary address is 10.0.0.0/8, and the value 5 is the administrative distance for the summary route.
- ✗
It creates a summary route 10.0.0.0/8 with a metric of 5, but only for the EIGRP process named TEST.
Why it's wrong here
The command is correct, but the metric value is actually the administrative distance, not the metric.
- ✗
It creates a summary route 10.0.0.0/8 with a hop count of 5.
Why it's wrong here
EIGRP does not use hop count; the value is the administrative distance.
- ✗
The command is invalid because the summary address must match the network statement exactly.
Why it's wrong here
The summary address can be a supernet of the network statement; this is valid.
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.
