| - | ====== Configuración MSTP en Aruba CX 6300 ====== | ||
| - | Este bloque muestra la conversión de una red que usaba **PVST/RPVST** hacia una arquitectura | + | |
| - | basada en **MSTP (Multiple Spanning Tree Protocol)**, requerida para ambientes modernos | + | ====== MSTP Configuration on Aruba CX 6300 ====== |
| - | con VSX, VLANs agrupadas y redes de gran escala. | + | |
| + | This document explains the recommended MSTP configuration for Aruba CX switches | ||
| + | and the differences between STP, RSTP, PVST/ | ||

| - | ===== ✅ Diferencias entre STP, RSTP, PVST/RPVST y MSTP ===== | + | ===== 1. Overview of Spanning Tree Protocol Types ===== |
| ==== ► STP (802.1D – Spanning Tree Protocol) ==== | ==== ► STP (802.1D – Spanning Tree Protocol) ==== | ||
| - | * Protocolo | + | * The original |
| - | * Convergencia lenta (30–50 | + | * Very slow convergence |
| - | * Ya no recomendado. | + | * Not recommended for modern networks. |
| - | ==== ► RSTP (802.1w – Rapid STP) ==== | + | ==== ► RSTP (802.1w – Rapid Spanning Tree Protocol) ==== |
| - | * Versión rápida del STP tradicional. | + | * Faster version of classic |
| - | * Convergencia mejorada. | + | * Still uses a **single instance** for all VLANs. |
| - | * **Una sola instancia** para TODAS las VLANs. | + | * Suitable only for small or simple environments. |
| - | * Adecuado para redes pequeñas, NO ideal para entornos complejos. | + | |
| - | ==== ► PVST / RPVST (Per-VLAN STP – Cisco) ==== | + | ==== ► PVST / RPVST (Per-VLAN STP – Cisco-style) ==== |
| - | * Una instancia | + | * Creates one STP instance |
| - | * Control granular por VLAN. | + | * High control, but heavy CPU/memory usage. |
| - | * Muy costoso en CPU/memoria en switches. | + | * On Aruba CX, RPVST exists only as a **compatibility mode**. |
| - | * En Aruba CX existe | + | * Not recommended for large environments or VSX cores. |
| - | * NO recomendado para redes grandes ni para VSX. | + | |
| ==== ► MSTP (802.1s – Multiple Spanning Tree Protocol) ==== | ==== ► MSTP (802.1s – Multiple Spanning Tree Protocol) ==== | ||
| - | * Agrupa **varias | + | * Maps multiple |
| - | * Reduce carga del switch. | + | * Scales extremely well. |
| - | * Mejora la estabilidad en redes multi-nodo. | + | * Fully supported and recommended on Aruba CX. |
| - | * Es el estándar recomendado para: | + | * Required for best performance with VSX. |
| - | * Aruba CX (6300/6400). | + | * Supports load-balancing per MST instance. |
| - | * VSX. | + | |
| - | * Redes con muchas VLANs. | + | |
| - | * Permite balanceo por instancias (ej. MSTI1, MSTI2…). | + | |

| - | ===== ✅ Recomendación General | + | ===== 2. Recommended Design |
| - | En **Aruba CX 6300/6400**, la mejor práctica oficial es: | + | For Aruba CX 6300/ |
| - | * **Usar MSTP siempre** | + | * Always use **MSTP**. |
| - | * Definir una sola **región MSTP** para todos los switches | + | * Use **one common MST Region** (same name and revision). |
| - | * Agrupar | + | * Group VLANs into 2–5 MST instances. |
| - | * Evitar completamente | + | * Avoid PVST/ |
| - | * Mantener el nombre de región y revisión idénticos en todos los nodos | + | * Keep MST region configuration identical on all switches. |
