[User]
Routing table:
C 1.1.1.0/24 is directly connected, Gi0/0
O 2.2.2.0/24 [110/10] via 1.1.1.3
S 2.2.2.0/24 [1/0] via 3.3.3.3
S 3.3.3.0/24 [1/0] via 1.1.1.2

Question: Analyze.

[Assistant]
<reasoning>
1. Recursive static overrides OSPF.
2. Suboptimal.
</reasoning>
<answer>
WARNING: Recursive static route overriding dynamic OSPF route.
