Add Service Tags to Route Tables/UDR
Include the ability to add Service Tags to UDRs. We have experienced that while many times services require NSGs to be open for a Service, many users have a default route in the Route Tables to push traffic through network virtual appliances. To circumvent having to put an entire datacenter range IP on UDRs to get services to work, there should be Service Tags in the UDR destination field in order to be able to add specific services the ability to talk to VNET-joined services. A good example of this is API Management. While the team does not support a default route. Technically, a default route and adding the ApiManagement ServiceTag IP ranges to the UDRs with NextHopType Internet is enough to get it to work anyway.
This is good feedback, we are looking into supporting this, stay tuned!
