darnodo 61a792df52 Enhance DC1 and DC2 topology configuration by adding access layer switches and host connections 
- Updated comments for clarity on leaf and border leaf layers
- Added access layer switches for both DC1 and DC2 with management IPs
- Established connections between access switches and their respective leaf switches
- Defined host devices for both DC1 and DC2, connected to local access switches
- Removed redundant host connection definitions and streamlined link configurations
