La commande no ip redirects apparait optionnellement dans la d\u00e9claration d’une interface. Elle indique que le routeur ne doit ni g\u00e9n\u00e9rer, ni accepter de paquets ICMP Redirect.<\/p>\n
Les paquets ICMP redirect sont g\u00e9n\u00e9r\u00e9s dans les conditions suivantes:<\/p>\n
* La machine A consid\u00e8re que la route vers B passe par le routeur R
\n * Le routeur R re\u00e7oit de la part de A un paquet destin\u00e9 \u00e0 B. Or, le routeur R constate qu’il a une route directe \u00e0 la fois vers A et B par la m\u00eame interface I. Le routeur R consid\u00e8re donc que A aurait pu envoyer directement le paquet vers B, sans passer par lui.
\n * Le routeur R transmet le paquet vers B et envoie \u00e0 A un paquet ICMP redirect demandant \u00e0 A de modifier ses tables de routage de fa\u00e7on \u00e0 acc\u00e9der directement \u00e0 B. <\/p>\n
L’utilisation de paquets ICMP redirects pourrait alt\u00e9rer la politique de routage d\u00e9finie par l’administrateur du r\u00e9seau. Il est donc prudent de rejeter ces paquets. <\/p>\n
To enable the sending of Internet Control Message Protocol (ICMP) redirect messages if the Cisco IOS software is forced to resend a packet through the same interface on which it was received, use the ip redirects command in interface configuration mode. To disable the sending of redirect messages, use the no form of this command.<\/p>\n
