Step 1 = Create a Customer Gateway (CGW) in AWS. Step 2 = Create a Virtual Private Gateway (VGW) in AWS. Step 3 = Create a site-to-site VPN connection in AWS. Step 4 = Configure the IOS XE router with the required IPsec VPN parameters and routing settings. Step 5 = Verify and test the VPN connection.

The process of configuring a site-to-site VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS) involves several steps12.

• Create a Customer Gateway (CGW) in AWS: This is the first step where you define the public IP address of your on-premises Cisco IOS XE router in AWS1.
• Create a Virtual Private Gateway (VGW) in AWS: This involves creating a VGW and attaching it to the VPC in AWS1.
• Create a site-to-site VPN connection in AWS: After setting up the CGW and VGW, you then create a site-to-site VPN connection in AWS. This involves specifying the CGW, VGW, and the static IP prefixes for your on-premises network1.
• Configure the IOS XE router with the required IPsec VPN parameters and routing settings: After the AWS side is set up, you configure the on-premises Cisco IOS XE router with the required IPsec VPN parameters and routing settings2.
• Verify and test the VPN connection: Finally, you verify and test the VPN connection to ensure that it is working correctly12.

The process of configuring an AppGoE service node for WAN optimization for applications that are hosted in the cloud using Cisco vManage for C8000V or C8500L-8S4X devices involves several steps12.

• Navigate to Configuration, select Templates, and then select Device Templates: This is the first step where you navigate to the Templates section in the Configuration menu of Cisco vManage1.
• Click Create Template, select From Feature Template, and then select the device model: In this step, you create a new template for the device model from the feature template1.
• Select Device, select Service Node, and then set Template Name and Description: After setting up the template, you select the device and the service node, and then set the template name and description1.
• Attach the device template to the device: Finally, you attach the created device template to the device1.

The problem is that the site-list “All-Site” has a higher match sequence than the site-list “Hub”, which means that the policy for “All-Site” will take precedence over the policy for “Hub” for any site that belongs to both lists. This creates a conflict and prevents the engineer from adding a new centralized control policy in Cisco vManage. To resolve this issue, the site-list “All-Site” should be configured with a new match sequence that is lower than the sequence for site-list “Hub”, so that the policy for “Hub” will be applied first and then the policy for “All-Site” will be applied only to the remaining sites that are not in the “Hub” list. References :=
