Bad Request error RRS feed

  • Question

  • Hi,

    I have three resource groups RG1, RG2 and RG3.

    RG1 has a VNET that I have created via ARM.

    RG2 has a VNET that I have created via ARM.

    RG3 has 3 NetworkInterfaces (Nic1, Nic2 and Nic3). Nic1 is an internal interface. Nic2's subnet is referencing RG1's VNET. Nic3's subnet is referencing RG2's VNET. I am referencing is following this syntax https://azure.microsoft.com/en-us/documentation/articles/resource-group-template-functions/#resourceid.

    In the above scenario Nic1 and Nic2 are successfully created via ARM but Nic3 throws a Bad Request error.

    Any reason why Nic2 works and Nic3 does not?

    Regards,

    Satheesh

    Single Azure VM can participate in multiple subnets within the same vNet but not beyond that.
