Merci pour ces réponses,
Alors, oui, j'ai pas mis toute la table de routage.. désolé, je voulais pas
vous submerger.
Je me permets donc de la coller ci-dessous.
En fait, ce qui m'inquiète, c'est que le 10.100.2.254, c'est le switch
lui-même sur laquelle il y a cette table de routage.
et 172.16.7.2, c'est notre sortie vers le firewal.
donc, il sait qu'il peut router les paquets vers lui même ? c'est Bizarre,
non ?
Ou alors, si je vous dis qu'on fait du HSRP et que si ce switch là tombe,
c'est un autre switch qui est censé faire le routage (mais du coup, sur la
même adresse de passerelle), ça vous semble plus probable ?
