Answer 1

To reset the private peering configuration in your Azure ExpressRoute circuit, you need to follow these steps:

Disable the Peering: In the Azure portal, locate your ExpressRoute circuit and navigate to the private peering configuration settings. Uncheck the "Enable" option to disable the peering. This action will shut down the Border Gateway Protocol (BGP) session for both the primary and secondary connections of your ExpressRoute circuit.

Enable the Peering: After disabling the peering, re-enable it by checking the "Enable" option again.

Regarding the time it takes for a peering connection to re-establish, it typically takes between 15 to 30 minutes. This duration may vary based on several factors, including network conditions and the specific configuration of your environment.

For more detailed guidance, you can refer to the Azure documentation on resetting circuit peerings:
