Intervalan routing

It offers a range of different materials from the most famous and biggest network vendors Cisco, At this step inter-VLAN routing can be configured on the router. By default all interfaces on a switch are switchports layer 2 but we can change them to routed ports layer 3. The interfaces on the router are configured as the default gateways for the VLANs configured on the switch.

When you take into consideration that most trojans and viruses perform an initial scan of the network before attacking, an administrator can smartly disable ICMP echoes and other protocols used to detect a live host, avoiding possible detection by an attacker host located on a different VLAN.

This interface accepts traffic from all the VLANs and determines the destination network based on the source and destination IP in the packets. For the most part of this course, we have been primarily focused on LAN technologies, many enterprises span over large geographical distances.

In this type of inter-VLAN routing, the interface connecting the router to the switch is usually a trunk link.

The Professional person behind When the router receives the tagged traffic, it forwards the traffic out to the subinterface that has the destination IP address. To create a subinterface which will be used to route for VLAN 10, we will use the command shown below.

There are two ways in which inter-VLAN routing can be accomplished. Our task is to configure inter-VLAN routing on the router and the switch and ensure that all devices can communicate at the end of the lab.

When you take into consideration that most trojans and viruses perform an initial scan of the network before attacking, an administrator can smartly disable ICMP echoes and other protocols used to detect a live host, avoiding possible detection by an attacker host located on a different VLAN.

The user nodes in the VLANs forwards traffic to the router which then forwards the traffic to the destination network regardless of the VLAN configured on the switch.

When the router receives the frame, it compares the destination IP address by referring to its routing table so as to know to which interface it should send the data towards the destination node. In our example, the command needed to link VLAN 10 to this subinterface is shown below: A routed port is the exact same interface as what we use on a router.

The use of VLANs means that users would not be able to communicate across departments, i. I bookmarked it on my browser to check it out periodically: Here you will find the configuration of each device.

This confirms that the router knows of the two VLANs and therefore traffic can flow between them. As you can see in the diagram below, the router is connected to the switch AS1 using a single, physical network connection. 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.

This interface accepts traffic from all the VLANs and determines the destination network based on the source and destination IP in the packets.

Gokhan Kosem is the Backbone Achitect and provides world class education allowing people to Certify with great marks.

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 configured on the switch.

X and Inter-vlan I have read from cisco sites that X with Lan base supports up to 16 static routes however I believe this is a layer 2 switch. One of my confusion is that would I be able to do Inter-vlan routing with this. Introduction.

This document explains how to configure interVLAN routing with Cisco Catalyst // series switches. The document provides a sample configuration for interVLAN routing with a Catalyst series switch that runs enhanced multilayer image (EMI) software in a typical network scenario.

Routing between the VLANs can be done using layer 3 switch or use more popular form of inter-vlan routing called router on a stick. Layer 3 switches are pretty expensive which is the main reason why router on a stick configuration is popular. Inter-VLAN routing will allow the VLAN10 and VLAN20 networks to communicate with each other through the switch.

You can also set up Inter-VLAN routing on the EdgeRouter (example article here). The advantage of using the EdgeSwitch is that all traffic between VLAN10 and VLAN20 does not have to pass through the router.

In this tutorial we will learn about InterVLAN Routing. What is InterVLAN routing?

As we learned, devices within a VLAN can communicate with each other without the need of Layer 3 routing. But devices in separate VLANs require a Layer 3 routing device to communicate with one another.

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.
