Overview

This lab demonstrates how to connect two different subnets in Azure using a virtual appliance and routing tables. By configuring routing between the subnets via a virtual appliance, you can control and manage the traffic flow between them.

Prerequisites

Before starting the lab, make sure you have the following:

An Azure subscription Access to the Azure portal Basic understanding of Azure networking concepts such as subnets, virtual networks, and routing A virtual appliance (NVA - Network Virtual Appliance) deployed in your Azure environment

Create a Resource Group:

Create a resource group named "cisco-vnet".

az group create --name cisco-vnet --location <your_location>

Create 3 Subnets:

Create three subnets:

• usa-zone,
• jpan-zone,
• nva-zone.

Assign IP ranges for each subnet:

• usa-zone: 10.10.0.0/24
• jpan-zone: 10.20.0.0/24
• nva-zone: 10.30.0.0/24

Create 3 Virtual Machines and Assign to Subnets:

Create three virtual machines, one for each subnet, and assign each virtual machine to its corresponding subnet.

Enabel ip forwding in the vna machine

" " In this section, turn on IP forwarding for the operating system of the vm-nva virtual machine to forward network traffic.

sudo vim /etc/sysctl.conf

In the Vim editor, remove the # from the line net.ipv4.ip_forward=1

Uncomment the next line to enable packet forwarding for IPv4
net.ipv4.ip_forward=1

Create a route table :

create a simple routing tabel called highway 59 and create a route called usa_to_jpan

• add name

• destaion

• nextope address "ip nva"

• type virtual appliance

  add source route address

• Select Subnets in Settings.

• Select + Associate.

• Enter or select the following information in Associate subnet:

Testing Connectivity Between VMs

To trace the routing of network traffic from vm-usa to vm-jpan, execute the following command:

tracepath 10.20.0.4

After executing the above command, please reboot the VMs and verify the connectivity
