MPLS L3 VPN allows companies to offer Layer 3 VPN services with advantages like scalability, security, and support for duplicate IP addresses and different network topologies. The key components that enable this are VRF tables on PE routers that separate routing information for each customer to avoid duplicate IP issues, and MP-BGP which customizes VPN routing information using a Route Distinguisher, VPN label, and Route Target to support different VPN topologies. MPLS L3 VPN provides services like multi-homed sites for redundancy, hub-and-spoke networks, internet access with security, and extranets for inter-company communication.
How to configure vlan, stp, dtp step by step guideIT Tech
The document provides step-by-step instructions to configure VLANs, VTP, STP, and DTP on Cisco switches and a router. It describes how to configure a VTP server, create VLANs 10 and 20, assign ports and PCs to each VLAN, configure trunk ports between switches, and configure a router interface for each VLAN to allow inter-VLAN communication. The configurations are verified by checking STP port status and pinging between PCs in different VLANs.
The document discusses the configuration of static MPLS label switched paths (LSPs) across a network topology consisting of routers in various cities. It describes how each router is configured to either push a label, swap a label, or pop the top label as packets traverse the LSP from Jakarta to Makasar and back. Traceroute outputs are provided to show the functioning LSP paths versus normal IGP routing. Complete configuration snippets are included in an appendix.
VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual
Local Area Networks (VLAN) on the whole local area network.[1] To do this, VTP carries VLAN
information to all the switches in a VTP domain. VTP advertisements can be sent over ISL, 802.1Q, IEEE
802.10 and LANE trunks. VTP is available on most of the Cisco Catalyst Family products.

Conférence de Jérôme Petazzoni (Pilot Systems) à Solutions Linux 2009.
La virtualisation réunit les avantages techniques d'un serveur dédié et d'un environnement mutualisé : les performances et la sécurité sont au rendez-vous, pour un coût opérationnel optimal. Contrairement à un serveur dédié, dont l'évolution nécessite des interventions matérielles (et des interruptions de services), un serveur virtualisé peut être reparamétré en quelques minutes, avec des interruptions de services minimes (voire nulles). Cette présentation montre comment tirer parti de la virtualisation pour l'hébergement des applications critiques de l'entreprise, en particulier dans les environnements Open Source utilisant Xen et Debian GNU/Linux.

WeOS création de réseaux et de réseaux virtuels VLANFabian Vandendyck
Cette fiche applicative présente la création de réseaux dans un switch Westermo. Nous aborderons tout d’abord la configuration des réseaux virtuels VLAN et nous expliquerons à partir d’eux comment créer des réseaux routés.
Fiche projet réseau local d'une entreprise moderne Mohamed Boubaya
L’objet de ce projet est de proposer une solution de conception d’un réseau local d’une entreprise moderne.
L’entreprise moderne traite de grandes quantités d'informations aussi nombreuses que variées. Ainsi, elle a besoin de grande capacité de stockage ainsi que d'une puissance de calcul élevée. Les ressources matérielles et logicielles nécessaires n'étant pas à la portée de toutes les entreprises, le Cloud Computing est donc la solution pour résoudre ce genre de problème.

Exercice 2.5.1 configuration de base d'un commutateur
VTP(Virtual Trunking Protocol)
1. VTP(Virtual Trunking Protocol)
C’est un protocole propriétaire Cisco de niveau 2
Il permet de configurer les Vlan sur un seul
commutateur
Cette configuration, ainsi que les éventuelles
modifications/mises à jour sont ensuite transmise
automatiquement aux autres commutateurs, via les
ports taggués (trunk)
3. Importance du VTP
Imaginons que nous devons configurer plusieurs VLANs
dans notre réseau
Créer 3 VLANs sur un switch est une opération de
configuration rapide
Créer 5 VLANs sur 4 switchs devient une opération de
configuration plus longue
Mais Créer 70 VLANs sur 90 switchs est alors une
opération de configuration fastidieuse avec une
probabilité d’erreur élevée
4. Importance du VTP
c’est là que le VTP prend toute son importance
Il sert à la propagation de création, suppression,
modification de VLAN sur tous les switchs de notre
réseau à partir d’un seul switch
5. Fonctionnement du VTP
Les messages VTP diffuse des annonces de création, de
suppression ou de modification de VLAN
Cette diffusion s’effectue à travers tous les switchs
grâce à une trame niveau 2 avec une adresse de
destination MAC multicast bien particulière qui est 01-
00-0C-CC-CC-CC
6. Architecture du VTP
Le switch possède 3 modes VTP:
-VTP Client
-VTP Transparent
-VTP Server (actif par défaut)
10. Synchronisation
1)A chaque création/suppression/modification de VLAN,
une variable appelée RN “Revision Number”
s’incrémente (initialement 0 puis 1 puis 2 puis 3…)
2) A chaque création/suppression/modification de VLAN,
le switch Server envoi un message VTP avec la nouvelle
valeure du RN
11. Synchronisation
3)Les autres switchs compare le RN reçu du
switch Server avec le RN qu’ils stockent en local, si ce
dernier est plus petit (logiquement) alors les switchs se
synchronisent avec le Server et récupère la nouvelle
base de données des VLANs
Par défaut, le RN est envoyé automatiquement dès une
création/suppression/modification de VLAN puis
envoyé toutes les 5 minutes
13. VTP Prunning
VTP Prunning permet de faire des économies de bande
passante
La fonction VTP Pruning s’active à partir du switch
Server
C’est une commande optionnelle
14. Remarques sur VTP
Les messages VTP se propagent sur les liens configurés
en Trunk (norme 802.1Q) et pas en Access
VTP ne gère que la plage de VLAN comprise entre 1 et
1005. La plage étendue 1006 à 4096 n’est pas
supportée. Pour cela, il faut basculer en mode
Transparent sur tous les switchs et créer ses VLANS
étendus(>1005) à la main
15. Remarques sur VTP
Il existe 3 versions de VTP(1,2 et3), mais il faut vérifier
qu’une et une seule version est active sur le réseau
pour éviter les surprises (car v1 et v2 sont
incompatibles entre elles)
La configuration VTP n’est pas visualisable dans la
running-config mais stockée dans le
fichier vlan.dat situé dans la flash ( show flash: pour
voir le fichier)
16. Configuration du VTP
Configurer un domaine VTP qui permet à tous les
switchs d’être dans le même “groupe d’amis”
Configurer le mode de votre switch (client, transparent
ou server)
Activer la fonction pruning (optionnel)
Configurer un mot de passe pour sécuriser les
messages VTP (optionnel)
Activer la version 2 ou 3 de VTP (version 1 active par
défaut) (optionnel)
17. Configuration du VTP
Switch> enable
Switch# configure terminal
Switch(config)# vtp domain TEST // configuration du
domaine VTP qu’on appelle TEST
Switch(config)# vtp mode server //configuration du
mode server
Switch(config)#vtp pruning //activation de la fonction
pruning a partir du switch server
18. Configuration du VTP
Switch(config)#vtp password cisco1234 //configuration
d’un mot de passe vtp (cisco1234)
Switch(config)#vtp version 2 //activation de la version
2 du vtp, il faut l’activer sur tous les switchs
19. Vérification de la configuration du VTP
Switch#show vtp status
VTP Version : 2
Configuration Revision : 1
Maximum VLANs supported locally : 255
Number of existing VLANs : 5
VTP Operating Mode : Server

Notes de l'éditeur
Commutateur=switch.
Concentrateur=hub
VTP Client: switch qui reçoit, se synchronise et propage les annonces VTP
VTP Transparent: switch qui ne traite pas les annonces VTP
VTP Server: switch qui crée les annonces VTP
Le switch en mode Server permet à l’administrateur de faire toute modification sur les VLANs et de propager automatiquement ses modifications vers tous les switchs du réseau.
Le switch en mode Client ne permet pas à l’administrateur de faire des modifications sur les VLANs. Vous recevez un message d’erreur quand vous essayez de créer un VLAN.
Le switch en mode Transparent permet à l’administrateur de faire toute modification sur les VLANs en local uniquement et donc ne propage pas ses modifications vers tous les switchs du réseau. Très pratique pour des maquettes!
Pour mettre RN a 0 on passe au mode transparent
Les switchs se synchronisent avec le RN le plus grand
Explication: imaginons qu’un switch reçoit les VLANs 1 et 2 mais qu’aucunes de ses interfaces appartiennent au VLAN 2. Lorsque le switch voisin lui enverra des trames du VLAN 2, ce switch les supprimera car aucune de ses interfaces appartiennent à ce VLAN. Il est donc inutile que le switch voisin lui envoi du trafic pour le VLAN 2.
On active alors la fonction VTP pruning pour avertir le switch voisin de ne pas lui envoyer de trafic pour ce VLAN.
VTP server est configure par defaut sur les switchs
Version par defaut sur les switchs est la version 1
VTP Version: affiche quelle est la version maximum supportée par le switch (ici le switch supporte les versions 1 et 2). Attention, ce n’est pas forcément celle active!
Configuration Revision: en mode server, elle débute à 1. En mode transparent, elle ne sert pas et donc mise à 0.
Maximum VLANs supported locally: nombre maximum de VLAN que le switch supporte. Dépend du type de switch (ici un 2960)
Number of existing VLANs: nombre de VLANs présents dans le switch (par défaut, les VLANs 1, 1002 à 1005 sont présents donc = 5)
VTP Operating Mode: Server, Client ou Transparent
VTP Domain Name: nom de votre “groupe” d’amis
VTP Pruning Mode: activation/désactivation de la fontion de pruning
VTP V2 Mode: c’est ici qu’on peut vérifier si la version 2 est bien activée (ou la version 3 si le switch la supporte)
VTP Traps Generation: permet d’envoyer des traps SNMP vers un serveur pour prévenir les administrateurs lorsqu’il y a un changement au niveau VTP (par exemple lors de la création d’un VLAN)
MD5 digest: affiche le hash du mot de passe précédent (cisco123 dans notre exemple)
Configuration last modified by: affiche quel est le dernier switch qui a fait une modification de VLANs (on peut avoir plusieurs switch Server dans un réseau)
visualiser si le mot de passe a bien été tapé
On remarque que tous les compteurs sont à 0, ce qui est logique car pour le moment, je n’ai pas encore créer/supprimer/modifier des VLANs.
