Create an Amazon Direct Connect public virtual interface

When you create a public virtual interface, it can take up to 72 hours for us to review and approve your request.

To provision a public virtual interface
  1. Open the Amazon Direct Connect console at https://console.amazonaws.cn/directconnect/v2/home.

  2. In the navigation pane, choose Virtual Interfaces.

  3. Choose Create virtual interface.

  4. Under Virtual interface type, for Type, choose Public.

  5. Under Public virtual interface settings, do the following:

    1. For Virtual interface name, enter a name for the virtual interface.

    2. For Connection, choose the Direct Connect connection that you want to use for this interface.

    3. For VLAN, enter the ID number for your virtual local area network (VLAN).

    4. For BGP ASN, enter the Border Gateway Protocol Autonomous System Number of your on-premises peer router for the new virtual interface.

      The valid values are 1-2147483647.

  6. Under Additional settings, do the following:

    1. To configure an IPv4 BGP or an IPv6 peer, do the following:

      [IPv4] To configure an IPv4 BGP peer, choose IPv4 and do one of the following:

      • To specify these IP addresses yourself, for Your router peer ip, enter the destination IPv4 CIDR address to which Amazon should send traffic.

      • For Amazon router peer IP, enter the IPv4 CIDR address to use to send traffic to Amazon.

      [IPv6] To configure an IPv6 BGP peer, choose IPv6. The peer IPv6 addresses are automatically assigned from Amazon's pool of IPv6 addresses. You cannot specify custom IPv6 addresses.

    2. To provide your own BGP key, enter your BGP MD5 key.

      If you do not enter a value, we generate a BGP key. If you provided your own key, or if we generated the key for you, that value displays in the BGP authentication key column on the virtual interface details page of Virtual interfaces.

    3. To advertise prefixes to Amazon, for Prefixes you want to advertise, enter the IPv4 CIDR destination addresses (separated by commas) to which traffic should be routed over the virtual interface.

      Important

      You may add additional prefixes to an existing public VIF and advertise those by contacting Amazon support. In your support case, provide a list of additional CIDR prefixes you want to add to the public VIF and advertise.

    4. (Optional) Add or remove a tag.

      [Add a tag] Choose Add tag and do the following:

      • For Key, enter the key name.

      • For Value, enter the key value.

      [Remove a tag] Next to the tag, choose Remove tag.

  7. Choose Create virtual interface.

  8. Download the router configuration for your device. For more information, see Download the router configuration file.
