Peering networks...

Question

How to peer 2 vnets in Azure ? Can you provide me some guidance ...

Answer 1

Hi,

Thank you for posting the question to the Q&A forum.

Virtual network peering enables you to seamlessly connect two or more Virtual Networks in Azure. The virtual networks appear as one for connectivity purposes. The traffic between virtual machines in peered virtual networks uses the Microsoft backbone infrastructure. Like traffic between virtual machines in the same network, traffic is routed through Microsoft's private network only.

You can find how to peer the 2 virtual networks on this link below: https://learn.microsoft.com/en-us/azure/virtual-network/tutorial-connect-virtual-networks-portal

I hope the above information can help you.

Hello @Dragan Stojkoski !

There are multiple ways to peer two VNETs in Azure. Most intuitive are using Azure Portal or Azure CLI.

For Azure Portal, you can refer to:
https://learn.microsoft.com/en-us/azure/virtual-network/tutorial-connect-virtual-networks-portal
https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-manage-peering?tabs=peering-portal#create-a-peering

Basically you just need to go to the VNET in Azure Portal -> Peerings -> Add -> fill the details

For Azure CLI, you can use:
az network vnet peering create -g MyResourceGroup -n MyVnet1ToMyVnet2 --vnet-name MyVnet1 \
--remote-vnet MyVnet2Id --allow-vnet-access

Reference: https://learn.microsoft.com/en-us/cli/azure/network/vnet/peering?view=azure-cli-latest#az-network-vnet-peering-create

Hello @Dragan Stojkoski ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand that you would like to know how to peer 2 Vnets in Azure.

Azure supports the following types of peering:

• Virtual network peering: Connecting virtual networks within the same Azure region.
• Global virtual network peering: Connecting virtual networks across Azure regions.

Limitations & constraints of Vnet peering:
You cannot peer two VNets with matching or overlapping address ranges.
https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-faq#can-i-peer-two-vnets-with-matching-or-overlapping-address-ranges
Resources in one virtual network can't communicate with the front-end IP address of a Basic Internal Load Balancer (ILB) in a globally peered virtual network.
Some services that use a Basic load balancer don't work over global virtual network peering.
Refer: https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview#constraints-for-peered-virtual-networks

You can peer 2 Vnets from the same subscription or belonging to different subscriptions.
Refer: https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview#next-steps

To create Vnet peering between 2 Vnets in same subscription, please refer the below step by step tutorial:

Kindly let us know if the above helps or you need further assistance on this issue.
