Step 1: Use Direct Connect or VPN to Communicate at Layer 3 Scenarios An enterprise switch establishes a Layer 2 network based on a Layer 3 network between an on-premises data center and a VPC.
VPN is located in this subnet.
Enabling Communications Between an On-Premises Data Center and the Cloud Using an Enterprise Switch Overview Server-based Migration to the Cloud Without Business Interruption (VPN + Enterprise Switch) Server-based Migration to the Cloud Without Business Interruption (Direct Connect
The Direct Connect or VPN connection fails. Check the Direct Connect or VPN connection configurations. Direct Connect Network and Connectivity VPN Connection or Ping Failure
Virtual Private Network (VPN) Identity and Access Management (IAM) On IAM, you can assign different permissions to different users to control their access to enterprise switch resources.
An L2CG is a virtual tunnel gateway that can work with Direct Connect or VPN to establish network communications between cloud and on-premises networks at Layer 2.
You need to create a Direct Connect or VPN connection first by referring to Step 1: Use Direct Connect or VPN to Communicate at Layer 3.
You need to create a Direct Connect or VPN connection first by referring to Step 1: Use Direct Connect or VPN to Communicate at Layer 3.
Constraints on Communication at Layer 3 Figure 1 shows the Layer 3 network between on-premises data centers and VPCs using VPN or Direct Connect. Table 1 describes the pain points.
Step Description 1 Step 1: Use Direct Connect or VPN to Communicate at Layer 3 An enterprise switch establishes a Layer 2 network based on a Layer 3 network between an on-premises data center and a VPC.
The migration process is as follows: Use Direct Connect or VPN to allow the cloud and the on-premises tunnel subnets to communicate at Layer 3. The Layer 2 network used by an enterprise switch is based on the Layer 3 network between tunnel subnets.
Use Direct Connect or VPN to enable the local (Subnet-tunnel-L01) and remote (Subnet-tunnel-R01) tunnel subnets to communicate at Layer 3. 2 Create an enterprise switch and specify a tunnel subnet.
If you want to use a VPN connection together with an enterprise switch, submit a service ticket to check whether your connection supports VXLAN interconnection with an enterprise switch. If your connection does not support this, contact customer service.
