Hi,
It depends on your network requirement, budget and business goals.
In general data center's 3 Tier design (Core/Agg/Access), L3 connection is recommended between CORE and Agg layers.
Below is typical 3 Tier Design requirement.
Layer | Switch Type | Port Speed | Config | Other |
Core | Modular | 10GE | Layer 3 | Campus hand off |
Aggregation | Modular | 10GE | Layer 2/3 boundary | Services (optional) |
Access | Fixed or Modular | GE/10GE | Layer 2 | ToR or MoR |
