Given this configuration on router R2: ```
ip vrf CUSTOMER_D
rd 100:1 !
interface GigabitEthernet0/0 ip vrf forwarding CUSTOMER_D ip address 192.168.2.1 255.255.255.0
!
router ospf 1 vrf CUSTOMER_D network 192.168.2.0 0.0.0.255 area 0
``` What will happen when this configuration is applied?
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
✓
OSPF will run on GigabitEthernet0/0 and form adjacencies within VRF CUSTOMER_D.
The OSPF process is tied to VRF CUSTOMER_D, so it only runs on interfaces that belong to that VRF. The network command matches the interface, so OSPF will form adjacencies on that interface within the VRF.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
OSPF will run on GigabitEthernet0/0 and form adjacencies within VRF CUSTOMER_D.
Why this is correct
This is correct. The OSPF process is VRF-aware and will operate only on interfaces in that VRF.
- ✗
OSPF will fail because the OSPF process must be configured globally, not under the VRF.
Why it's wrong here
Incorrect. OSPF can be configured per VRF using the 'vrf' keyword.
- ✗
OSPF will run on all interfaces, including those not in VRF CUSTOMER_D.
Why it's wrong here
Incorrect. The VRF keyword restricts OSPF to interfaces in that VRF.
- ✗
The network command is invalid because it uses a wildcard mask instead of a subnet mask.
Why it's wrong here
Incorrect. OSPF uses wildcard masks in network statements.

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.
