This document explains how to configure interVLAN routing with Cisco Catalyst 3750/3560/3550 series switches. The document provides a sample configuration for interVLAN routing with a Catalyst 3550 series switch that runs enhanced multilayer image (EMI) software in a typical network scenario. The document uses a Catalyst 2950 series switch and a Catalyst 2948G switch as Layer 2 (L2) closet switches that connect to the Catalyst 3550. The Catalyst 3550 configuration also has a default route for all traffic that goes to the Internet when the next hop points to a Cisco 7200VXR router. You can substitute a firewall or other routers for the Cisco 7200VXR router. These VLANs are the three VLANs that the user defines:
VLAN 2—user VLAN
VLAN 3—server VLAN
VLAN 10—management VLAN
The default gateway configuration on each server and host device must be the VLAN interface IP address that corresponds on the 3550. For example, for servers, the default gateway is 10.1.3.1. The access layer switches, which are the Catalyst 2950 and 2948G, are trunked to the Catalyst 3550 switch. The default route for the Catalyst 3550 points to the Cisco 7200VXR router. The Catalyst 3550 uses this default route to route traffic destined for the Internet. Therefore, traffic for which the 3550 does not have a routing table entry forwards to the 7200VXR for process.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
j ai une question j ai achete un routeur cisco 887VA-k9 , je le configuré avec la configuration ci- dessous
si je le lier avec mon pc portable sur l un de ses ports directement ça marche toute est bien ( la connexion internet + m...
