Notes from the Field
I have recently been involved with an implementation of Microsoft Peering for Expressroute with a large Australian customer and thought I would share the experience with you.
Firstly, and secondly, make sure that you read the specific guidance from Microsoft regarding prerequisites for Microsoft Peering. (See below)
Configure Microsoft peering for the circuit
Make sure that you have the following information before you proceed.
- A /30 subnet for the primary link. This must be a valid public IPv4 prefix owned by you and registered in an RIR / IRR.
