Examine the following EIGRP configuration on a Cisco IOS-XE device:
router eigrp 100 network 10.0.0.0 0.255.255.255 passive-interface default no passive-interface GigabitEthernet0/0
!
interface GigabitEthernet0/0 ip address 10.1.1.1 255.255.255.0
!
interface GigabitEthernet0/1 ip address 10.2.2.1 255.255.255.0
Which statement is true?
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
✓
EIGRP will form an adjacency only on GigabitEthernet0/0.
The 'passive-interface default' command sets all interfaces as passive, meaning they do not send or receive EIGRP hellos. The 'no passive-interface' command overrides this for specific interfaces.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
EIGRP will form adjacencies on both GigabitEthernet0/0 and GigabitEthernet0/1.
Why it's wrong here
Incorrect. Only GigabitEthernet0/0 is explicitly set to not be passive. GigabitEthernet0/1 remains passive and will not form adjacencies.
- ✓
EIGRP will form an adjacency only on GigabitEthernet0/0.
Why this is correct
Correct. GigabitEthernet0/0 is not passive, so it will send and receive hellos. GigabitEthernet0/1 is passive by default.
- ✗
EIGRP will not form any adjacencies because the network command does not match the interface subnets.
Why it's wrong here
Incorrect. The network 10.0.0.0 0.255.255.255 matches both interfaces (10.1.1.1 and 10.2.2.1).
- ✗
EIGRP will form adjacencies on all interfaces except those with 'passive-interface' configured.
Why it's wrong here
Incorrect. The 'passive-interface default' makes all interfaces passive unless overridden with 'no passive-interface'.
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.
