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

## 🔍 IP Address Validation

## 🏗️ Architecture Benefits
|
||||||
|
|
||||||
### No Conflicts With Your LAN ✅
|
### Why Access Layer?
|
||||||
|
|
||||||
|
1. **Scalability**: Each bay/rack gets its own switch
|
||||||
|
- Easy to add more bays: just add another access switch
|
||||||
|
- Leaf ports don't run out (48 port switch = 24 racks possible)
|
||||||
|
|
||||||
|
2. **Simplified Cabling**:
|
||||||
|
- Hosts only need 1 cable (to local access switch)
|
||||||
|
- Access switch dual-homes to MLAG leaf pair
|
||||||
|
- Reduces cross-rack cabling complexity
|
||||||
|
|
||||||
|
3. **Automation-Friendly**:
|
||||||
|
- Access switches are identical (same config template)
|
||||||
|
- Only variables: hostname, bay number, VLANs
|
||||||
|
- Easy to generate configs from data model
|
||||||
|
|
||||||
|
4. **Cost-Effective**:
|
||||||
|
- Access switches can be cheaper models (L2/L3 basic)
|
||||||
|
- Leafs reserved for VXLAN/EVPN (more expensive)
|
||||||
|
|
||||||
|
5. **Failure Domain Isolation**:
|
||||||
|
- Bay/rack failure contained to access switch
|
||||||
|
- Doesn't affect underlay routing
|
||||||
|
|
||||||
|
### Automation Implications

## 💡 Design Highlights
|
## 💡 Design Highlights
|
||||||
|
|
||||||
1. **Clean Separation**: Each DC has its own /16 (10.1.x.x and 10.2.x.x)
|
1. **4-Tier Architecture**: Spine → Leaf → Access → Host
|
||||||
2. **Consistent Numbering**: Same pattern in both DCs
|
2. **Clean Separation**: Each layer has distinct role
|
||||||
3. **Easy Troubleshooting**: IP tells you the location/role
|
3. **MLAG at Leaf Layer**: Access switches dual-home to leaf pairs
|
||||||
- `.0.x` = Loopback0 (router-id)
|
4. **Access Layer is L2**: Simplifies config, VLANs stretched via VXLAN
|
||||||
- `.1.x` = Loopback1 (VTEP)
|
5. **One Access Per Bay**: Realistic rack/bay topology
|
||||||
- `.10.x` = P2P links
|
6. **Automation-Ready**: Consistent patterns, easy templating
|
||||||
- `.255.x` = MLAG peer links
|
7. **Scalable**: Add bays by adding access switches
|
||||||
4. **Scalable**: Room for growth in each range
|
|
||||||
5. **No LAN Conflicts**: Completely avoids 192.168.x.x space
|
|
||||||
|
|
||||||
This addressing plan is production-ready and automation-friendly! 🎯
