Intervalan routing

The use of VLANs means that users would not be able to communicate across departments, i. We will learn how it works, consider the various methods that can be used to implement it, configure inter-VLAN routing using router-on-a-stick and traditional inter-VLAN routing, compare the two styles of implementation and finally verify and troubleshoot inter-VLAN routing. Introduction to inter-vlan routing When we learnt about VLANs, we said that each VLAN is usually on its own subnet, switches mainly operate at layer 2 of the OSI model and therefore they do not examine the logical addresses. Therefore, user nodes located on different VLANs cannot communicate by default.

R1 show ip route Codes: So why would you want to use a solution like this? Any layer 2 switch will do. The Cisco Catalyst is a layer 2 switch; the cheapest multilayer switch is the Cisco Catalyst Some of the disadvantages of this solution is that your router is a single point of failure and that traffic flows up and down on the same link which might cause congestion.

This switch has routing capabilities! This IP address can be used for computers as their default gateway. This configuration might look familiar if you worked with layer 2 switches before.

At least one access or trunk port should use this VLAN actively and it should be in spanning-tree forwarding mode. Method Status Protocol Vlan10 By default all interfaces on a switch are switchports layer 2 but we can change them to routed ports layer 3.

A routed port is the exact same interface as what we use on a router. Here you will find the configuration of SW1. If you like to keep on reading, Become a Member Now!

Introduction to inter-vlan routing

You may cancel your monthly membership at any time.RE: Inter VLAN routing with multiple VLANs For VLAN routing to work the VLAN interfaces need to have an IP Address, and the command ip routing needs to be run on the switch. Clients connecting to access ports will need to have an IP Address within the VLAN subnet, and have the VLAN IP Address as the default gateway.

This type of routing is called inter-VLAN routing. On a smart switch, you can set up inter-VLAN routing by creating a Layer 3 interface, that is, a switch virtual interface (SVI).

RE: Inter VLAN routing with multiple VLANs For VLAN routing to work the VLAN interfaces need to have an IP Address, and the command ip routing needs to be run on the switch. Clients connecting to access ports will need to have an IP Address within the VLAN subnet, and have the VLAN IP Address as the default gateway. If we want communication between these VLANs we’ll have to use a device that can do routing. In this example we’ll use a router for the job. R1 will need access to both VLANs so we’ll create a Q trunk between SW1 and R1.

By default, a port is enabled for bridging rather than routing. May 10,  · In this video, Keith Barker covers a inter-vlan routing including configuring a network with access ports, trunk ports, routing protocols.

To see all the videos in this playlist, you can go here. Inter-VLAN routing can be defined as a way to forward traffic between different VLAN by implementing a router in the network. As we learnt previously, VLANs logically segment the switch into different subnets, when a router is connected to the switch, an administrator can configure the router to forward the traffic between the various VLANs.

How to Configure Inter-VLAN Routing on Cisco Router and Layer 3 Switch? By Shais Last updated Apr 25, A step by step guide to configure Inter-VLAN Routing on the Cisco router or layer 3 switches. VLAN Routing Solution No InterVLAN Routing. And at last, InterVLAN routing! This is without a doubt the best VLAN routing solution out of all of the above.
