how can you tell the resiliency level of an existing (already provisioned) ExpressRoute Circuit?

Question

trying to copy a EXR Circuit 1:1 & there seems to be no way to tell what kindof resiliency level is attached to an existing circuit. I've looked through the GUI, the JSON info, etc.

AI answers my question like this:

The resiliency level of the circuit can be found under the type of Resiliency selected during the circuit creation process.

which is a circular answer & doesn't help.

Hi Erik Drueding,

Greetings,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

It sounds like you’re trying to determine the resiliency level of an existing Azure ExpressRoute circuit:

• To obtain the express route circuit. If you view these as metro, it suggests you're utilizing High Resiliency.
• High resiliency offers site diversity by splitting a single circuit across two sites.
• The first connection is established at one site and the second connection at a different site. The objective of ExpressRoute Metro is to mitigate the effect of edge-sites isolation and failures by introducing capabilities to enable site diversity.
• Site diversity is achieved by using a single circuit across paired sites within a metropolitan city, which offers resiliency to failures between edge and region.

Site resiliency for ExpressRoute

There are three ExpressRoute resiliency architectures that can be utilized to ensure high availability and resiliency in your network connections between on-premises and Azure. These architecture designs include:

• Maximum resiliency
• High resiliency
• Standard resiliency

Refer: https://learn.microsoft.com/en-us/azure/expressroute/design-architecture-for-resiliency#site-resiliency-for-expressroute

NOTE: the naming convention for Metro sites will utilize City and City2 to denote the two unique peering locations within the same metropolitan region. As an illustration, Amsterdam and Amsterdam2 are indicative of the two separate peering locations within the metropolitan area of Amsterdam. In the Azure portal, these locations will be referred to as Amsterdam Metro.
