ARM template for 2 nets in mutual peering

Question

I need to build a custom arm template that does the following:

• create virtual-network-1
• create virtual-network-2
• create peering from virtual-network-1 to virtual-network-2
• create peering from virtual-network-2 to virtual-network-1

I have created these resources manually, and generated the corresponding arm template, but when I try to run the template I receive a circular dependency error.

Any help is appreciated!
