Introduction
VLANs divide broadcast domains in a LAN environment.Whenever hosts in one VLAN need to communicate with hosts inanother VLAN, the traffic must be routed between them. This isknown as inter-VLAN routing. On Catalyst switches it isaccomplished by creating Layer 3 interfaces (Switch virtualinterfaces (SVI) ). This document provides the configuration andtroubleshooting steps applicable to this capability.
Note: This document uses a Catalyst 3550 as an example.However, the concepts can also be applied to other Layer 3switches that run Cisco IOS (for example, Catalyst 3560, 3750,Catalyst 4500/4000 Series with Sup II+ or later, or Catalyst6500/6000 Series that run Cisco IOS System software).
Prerequisites
Requirements
Catalyst switch models 3560, 3750, Catalyst 4500/4000 Serieswith Sup II+ or later, or Catalyst 6500/6000 Series that run CiscoIOS system software support basic InterVLAN routing features inall their supported software versions. Before you attempt thisconfiguration on a 3550 series switch, ensure that you meet thesprerequisites:
InterVLAN routing on the Catalyst 3550 has certainsoftware requirements to support interVLAN routing on theswitch. See this table to determine whether your switch ca
