Voir un scénario similaire avec le routeur Vyatta.

1. PRINCIPE

Nous allons tester dans cet troisième exemple un environement d'un niveau de difficuté moyen où deux routeurs (Cisco 3750 & Quagga B) sont reliés entre eux par deux aires OSPF dont une est de type stub (stub area).

Le routeur Quagga B et le routeur Cisco 2651 sont localisés dans une aire de type stub, ils ont des routes OSPF intra (O) et inter-aires (OIA) dans leur table de routage mais aucune route OSPF de type externe.
Pour atteindre, depuis les deux routers mentionnés ci-dessus des réseaux OSPF externes comme 10.200.1.1 dans notre étude, il y a une route OSPF par défaut vers le "border router" (routeur vyatta A).
Quagga A est appelé "border router" (routeur frontière) parce qu'il est à la fois dans l'aire 1 et l'aire 0 (backbone area).

Dans le cadre de notre étude, la route statique 10.200.1.1 est redistribuée dans OSPF au niveau du routeur Vyatta A pour créer "artificiellement" un réseau OSPF externe (OE2). A cause de l'aire stub, ce réseau ne doit pas se diffuser dans les tables de routages du router Vyatta B et du routeur Cisco 2651.

Fonctionnalités testées: (cliquez sur les liens internet pour avoir plus de détails sur un protocole) Paramétrage interfaces OSPF - backbone area OSPF - multi area OSPF - stub area Routage statique Redistribution - static vers OSPF Accès Telnet

3. CONFIGURATIONS

Vous devez configurer votre système Linux correctement pour pouvoir lancer Quagga avec succès. Référez-vous au tutorial Quagga pour de l'assistance.

LINUX CONFIGURATIONS

Vérifiez que les démons ospfd et zebra sont activés sur Quagga A et Quagga B:

#vim /etc/quagga/daemons

zebra=yes
bgpd=no
ospfd=yes
ospf6d=no
ripd=no
ripngd=no
isisd=no

Si vous avez effectués des changements dans vos fichiers daemon, redémarrez le service quagga:

#vim /etc/init.d/quagga restart

Stopping Quagga daemons (prio:0): ospfd zebra (bgpd) (ripd) (ripngd) (ospf6= d) (isisd).
Removing all routes made by zebra.
Nothing to flush.
Loading capability module if not yet done.
Starting Quagga daemons (prio:10): zebra ospfd.

Configurez le nom d'hôte (hostname) de Quagga A dans le fichier /etc/quagga/vtysh.conf:

#vim /etc/quagga/vtysh.conf

!
! Sample
!
! service integrated-vtysh-config
hostname Quagga_A
username root nopassword
!

Configurez le nom d'hôte (hostname) de Quagga B dans le fichier /etc/quagga/vtysh.conf:

#vim /etc/quagga/vtysh.conf

!
! Sample
!
! service integrated-vtysh-config
hostname Quagga_B
username root nopassword
!

N'oubliez pas d'activer la redirection IP (IP forwarding) sur le routeur Quagga A!
Il n'est pas nécessaire d'activer la redirection IP sur le routeur Quagga B parce qu'il n'a qu'une interface réseau.
