The following are a few common Express Connect scenarios:
Multimedia applications requires low network latency for optimal performance. However, latency can vary as the Internet does not provide a consistent performance when transferring data from one point to another. Alibaba Cloud Express Connect allows you to control how your data is routed over a dedicated line, providing a more consistent network experience as compared to Internet-based connections.
Using Alibaba Cloud Express Connect, you can build hybrid environments that require private connectivity with a combination of on-premise infrastructure, cloud technology and third-party cloud service providers that follow industry standard compliance requirements. Hybrid environments allow you to combine the elasticity and economic benefits of Alibaba Cloud Express Connect with the ability to utilize infrastructure that you have already provisioned .
Cross-regional, Cross-account Environments
Use Alibaba Cloud Express Connect to establish a connection between two VPCs in different regions. VPCs in different regions act as an extension of your datacenter. Connect the two VPCs through a secure and stable connection to provide seamless and faster data transfers that will help with automatic synchronization of users’ data between applications.

9. What are the specifications of the various Router Interface?
10. What are the prerequisites for using ExpressConnect?
You must have a registered Alibaba Cloud account with complete information.
You have VPC in Alibaba Cloud.
You must have a physical connectivity between your various locations. For physical connection setup, you can contact a carrier or buy a carrier leased line at Alibaba Cloud Market.
1. Why can't I buy Router Interface for inter-region connectivity?
Currently, the minimum specification of Router Interface for inter-region is is Small.1. Due to the special nature of the inter-region services, the console does not support direct self-purchase. However, Alibaba Cloud does provide offline service activation and procurement. You can submit an ticket or contact your customer manager for more details.
2. What is the pricing model for Express Connect？
Refer to the Express Connect Fee Structure.
1. How do I obtain the location of an Alibaba Cloud access point if I want to buy a leased line?
You can submit a ticket to obtain the geographic location of an access point. However, the Alibaba Cloud system will only assign the specific datacenter location to you after you procure the Physical Connection access fee on the Alibaba Cloud website.
2. Is physical connection redundancy supported?
Yes. You can apply the equivalent route mode to up to four physical connections. For details, refer to Best practice – redundant physical connection.
3. What interfaces and protocols does a physical connection support?
A physical connection to Alibaba Cloud supports the optical interface LC mode and electrical interface RJ45 mode. Currently, physical connections only support the Ethernet protocol, not the V.35, G.703, and other protocols.
4. Does a redundant physical connection support multi-carrier access or multiple access points?
Yes. We suggest you access Alibaba Cloud through different carriers at different access points to improve redundancy.
5. What routing modes does Express Connect support?
Currently, Express Connect only supports static routing.
6. Does Express Connect support network address translation (NAT)?
• NAT is currently not supported for Express Connect. When using Express Connect, users have to ensure no network address conflict on both ends of the connection.

8. Can I extend my local VLAN to VPC through Express Connect?
No. Currently, Alibaba Cloud only supports L3 interconnection.
9. How do I connect my physical hosting network to VPC through Express Connect?
You can rent a point-to-point leased line from a carrier or use a leased line of an Alibaba Cloud partner.
10. Can I interconnect multiple VPC instances through a physical connection?
Yes. A new VPC instance reuses the existing VBR by establishing a new VRouter interface with the VBR. For details, refer to Virtual Border Router.
11. How many VPC instances can be interconnected through one physical connection?
By default, each VRouter instance supports six VRouter interfaces. Therefore, one physical connection supports five VPC instances interconnected through the L3 interface.
12. Are the interconnected VPC instances isolated over the Physical Connection?
You can configure VLANs over the physical connection to isolate network data.
13. Which access point do I connect to if I want to use Zone A where my ECS instance is located?
Zone and access point are two concepts of region and they do not have a strict mapping relationship. You can choose the access point deployed at Alibaba’s POP point (network service provisioning point) in the corresponding region. POP points and zones share a common geographic location in some regions.
14. I have applied for a point-to-point leased line from a carrier to connect to an Alibaba Cloud access point. What VLANID should I use during VBR configuration?
If the device for leased line access in your physical hosting machine room supports the L3 port and you do not require VLAN-based VPC isolation over the physical connection, you can set VLANID to 0.
If you need to isolate data through VLAN, VLANID on both ends of the leased line must be the same.
