Hi, I have followed all the instructions on setting up a peering request. My ASN has also been approved but under connections, the connection state says "provisioningfailed" The entire setup was done on 27th of July 2020. Urgent assistance is requested.

    If you need urgent assistance then your best option is to open a support ticket directly with Microsoft.

    If you look in the portal and click on the error it should provide you more details on why provisioning failed, please provide this information.

    Hello @Varun Singhania ,

    Since you have mentioned ASN in your question, I believe you are referring to ExpressRoute peering and not Vnet peering.
    If that is the case, you can validate the below:

    If enabling a peering fails, check if the primary and secondary subnets assigned match the configuration on the linked CE/PE-MSEE. Also check if the correct VlanId, AzureASN, and PeerASN are used on MSEEs and if these values maps to the ones used on the linked CE/PE-MSEE. If MD5 hashing is chosen, the shared key should be same on MSEE and PE-MSEE/CE pair.

    Please refer : https://learn.microsoft.com/en-us/azure/expressroute/expressroute-troubleshooting-expressroute-overview

    Kindly let us know if you need any further assistance on this issue from our end.
