Express Route ARP Cache

Hopefully simple questions that I really cannot find direct answers for:

1, How long does an Express Route cache it's ARP entries?

2, Is it safe to delete and re-create the Private Peering from within the portal/PowerShell?

Thanks,

Mike

    @Michael Hale Thank you for your pateince while I was looking into this.

    1. The default ARP cache timeout value is 20 minutes.
    2. Regarding deleting and re-creating the circuit, I would suggest you to discuss this with your provider and do the same.

    Hope this helps. If you have any further questions/concerns, please so let us know.
    Thank you!
