## Controller & Compute

- **bond0 (2x pNIC)** → `mgmt/api`
    
    
    - VLAN: `Mgmt (untagged atau VLAN 10)`, `API internal (VLAN 11)`
    - MTU 1500 (bisa 9000 kalau end-to-end mendukung, tapi tidak wajib)
    - Mode: **LACP (802.3ad)** atau **active-backup**
- **bond1 (2x pNIC)** → `overlay/tunnel` (VXLAN/Geneve)
    
    
    - VLAN: `Overlay (VLAN 20)`
    - **MTU 9000** (disarankan)
    - Mode: LACP/active-backup
- **bond2 (2x pNIC)** → `external/provider`
    
    
    - Untagged/VLAN trunk sesuai design provider network
    - MTU 1500 (umum untuk publik)
    - Mode: LACP/active-backup
- **bond3 (2x pNIC)** → **Ceph**
    
    
    - Sub-interface `bond3.30` → **Ceph Public** (VLAN 30) **MTU 9000**
    - Sub-interface `bond3.31` → **Ceph Cluster** (VLAN 31) **MTU 9000**
    - Mode: LACP/active-backup

## **Prefix dan Segmentasi**

Gunakan subnet berbeda per fungsi:
