 When you select **Direct routing within virtual network** or **Direct routing within subne**t, a UDR with a virtual network next hop is created for local traffic routing within the same virtual network or subnet. However, if the destination CIDR is fully contained within the source CIDR under these selections and direct routing is selected, a UDR specifying a network appliance as the next hop won't be set up.

-In this article, you learn how to deploy a Spoke-to-Spoke topology with two hubs using Virtual Network Manager. This scenario is useful when you have a hub and spoke architecture in multiple Azure regions. In the past, customers with firewalls or network virtual appliances performed many manual operations to do cross-hub and spoke in the past. Users needed many user-defined routes(UDRs) to be set up by hand, and when there were changes in spoke virtual networks, such as adding new spoke virtual networks and subnets, they also needed to change user-defined routes and route tables. UDR management with Virtual Network Manager can help you automate these tasks.
