## Properties

- `bgpAsn`: number = 65000 — For customer gateway devices that support BGP, specify the device's ASN.

  You must specify either `BgpAsn` or `BgpAsnExtended` when creating the customer gateway. If the ASN is larger than `2,147,483,647` , you must use `BgpAsnExtended` .

  Default: 65000

  Valid values: `1` to `2,147,483,647`

- `bgpAsnExtended`: number — For customer gateway devices that support BGP, specify the device's ASN.

  You must specify either `BgpAsn` or `BgpAsnExtended` when creating the customer gateway. If the ASN is larger than `2,147,483,647` , you must use `BgpAsnExtended` .

  Valid values: `2,147,483,648` to `4,294,967,295`
