Azure VNet Peering

  • Setup peering from Hub Vnet to LMS Vnet
  • Selected "Use this virtual networks gateway or route server"
  • Setup peering from LMS Vnet to Hub Vnet
  • Selected "Use the remote virtual networks gateway or route service"

Azure Route Tables

  • Virtual network peering is a non-transitive relationship between two virtual networks.
  • In Azure "peer-to-peer transitive routing describes network traffic between two virtual networks that are routed through an intermediate virtual network with a router
  • For example VNet1 has peered with the VNet2 network, and VNet2 has peered with VNet3, but VNet1 and VNet3 are not connected. For network traffic to get from VNat1 to VNet3, it would have to go through the VNet2 network. This action is known as transitive routing.
