Azure Networking contd

Connecting Two Private networks in Azure

• To Connect two private networks in azure using private ips we have two options
  • Vnet Peering
  • Vnet to Vnet Connection
• condition: vnet address spaces should not collide
• Azure vnets have a default router in it Refer Here
• Create a vnet (app-net) in east us and one vnet (data-net) in west us.
• In each vnet try creating a vm
  • vm in east us will have public ip
  • vm in west us will not have public ip
• Now when we try communicating from app to data it will not work as their is no network infra
• Azure Vnet Peering can create this infra between two networks and also configure routing Refer Here
  
  
  
  
  
  
  
  
• Now private connectivity should be enabled by ip’s
  

Figure out answers for the below

• In Azure when we create a subnet it reserves 5 ipaddress we know 2 one is network id and other is broadcast address why other 3
• Try to create a vnet with address 192.168.0.0/24 and assume that you have run out of ip addresses now you want to expand network size is it possible? if yes how?
• What is hub-spoke
