Are there limits on the amount of data that I can transfer using AWS Direct Connect?
Technical
AWS Direct Connect | Networking & Content Delivery
No. You may transfer any amount of data up to the limit of your selected port speed.
What are the technical requirements for the connection?
Technical
AWS Direct Connect | Networking & Content Delivery
AWS Direct Connect supports 1000BASE-LX or 10GBASE-LR connections over singlemode fiber using Ethernet transport. Your device must support 802.1Q VLANs. See the AWS Direct Connect User Guide for more detailed requirements information.
What AWS region(s) can I connect to via this connection?
Technical
AWS Direct Connect | Networking & Content Delivery
Using direct connect gateway, you can connect to VPCs deployed in any AWS Region from this location. See the Direct Connect Gateway page to get more details.
Direct connect locations can also access the public resources in any AWS Region using a public virtual interface.
What Availability Zone(s) can I connect to via this connection?
Technical
AWS Direct Connect | Networking & Content Delivery
Using direct connect gateway, you can connect to VPCs deployed in any AWS Region Availability Zone(s) from this location. See the direct connect gateway page to get more details.
Are connections to AWS Direct Connect redundant?
Technical
AWS Direct Connect | Networking & Content Delivery
Each connection consists of a single dedicated connection between ports on your router and an Amazon router. We recommend establishing a second connection if redundancy is required. When you request multiple ports at the same AWS Direct Connect location, they will be provisioned on redundant Amazon routers.
Will I lose connectivity if my AWS Direct Connect link fails?
Technical
AWS Direct Connect | Networking & Content Delivery
If you have established a second AWS Direct Connect connection, traffic will failover to the second link automatically. We recommend enabling Bidirectional Forwarding Detection (BFD) when configuring your connections to ensure fast detection and failover. If you have configured a back-up IPsec VPN connection instead, all VPC traffic will failover to the VPN connection automatically. Traffic to/from public resources such as Amazon S3 will be routed over the Internet. If you do not have a backup AWS Direct Connect link or a IPsec VPN link, then Amazon VPC traffic will be dropped in the event of a failure. Traffic to/from public resources will be routed over the Internet.
Can I extend one of my VLANs to the AWS Cloud using AWS Direct Connect?
Technical
AWS Direct Connect | Networking & Content Delivery
No, VLANs are utilized in AWS Direct Connect only to separate traffic between virtual interfaces.
Does AWS Direct Connect offer a Service Level Agreement (SLA)?
Technical
AWS Direct Connect | Networking & Content Delivery
Not at this time.
What are the technical requirements for virtual interfaces to public AWS services such as Amazon EC2 and Amazon S3?
Technical
AWS Direct Connect | Networking & Content Delivery
This connection requires the use of the Border Gateway Protocol (BGP) with an Autonomous System Number (ASN) and IP Prefixes. You will need the following information to complete the connection:
A public or private ASN. If you are using a public ASN, you must own it. If you are using a private ASN, it must be in the 64512 to 65535 range.
A new unused VLAN tag that you select
Public IPs (/30) allocated by you for the BGP session
Amazon will advertise public IP prefixes for the region via BGP. Direct Connect customers in the North America will receive the public IP prefixes for all US regions. You must advertise public IP prefixes (/30 or smaller) that you own via BGP. For more details, consult the AWS Direct Connect User Guide.
What is an Autonomous System Number (ASN) and do I need one to use AWS Direct Connect?
Technical
AWS Direct Connect | Networking & Content Delivery
Autonomous System numbers are used to identify networks that present a clearly defined external routing policy to the Internet. AWS Direct Connect requires an ASN to create a public or private virtual interface. You may use a public ASN which you own, or you can pick any private ASN number between 64512 to 65535 range.
What IP address will be assigned to each end of a virtual interface?
Technical
AWS Direct Connect | Networking & Content Delivery
If you are configuring a virtual interface to the public AWS cloud, the IP addresses for both ends of the connection must be allocated from public IP space that you own. If the virtual interface is to a VPC and you choose to have AWS auto-generate the peer IP CIDR, the IP address space for both ends of the connection will be allocated by AWS in the 169.254.0.0/16 range.
Can I connect to the Internet via this connection?
Technical
AWS Direct Connect | Networking & Content Delivery
No.
If I have more than one virtual interface attached, can I exchange traffic between the two ports?
Technical
AWS Direct Connect | Networking & Content Delivery
Not for public Direct Connect virtual interfaces; but you can exchange traffic between the two ports in the same region if they are connecting to the same VGW.
