 This article describes how to enable and disable peerings of an ExpressRoute circuit using PowerShell. Peerings are enabled by default when you create them. When you disable a peering, the BGP session on both the primary and the secondary connection of your ExpressRoute circuit will be shut down. You'll lose connectivity for this peering to Microsoft. When you enable a peering, the BGP session on both the primary and the secondary connection of your ExpressRoute circuit will be established. The connectivity to Microsoft will be restored for this peering. You can enable and disable peering for Microsoft Peering and Azure Private Peering independently on the ExpressRoute circuit.
