For our simulated Datacenter Router we will need to use a SSH keypair to access. When you create a KeyPair in AWS, the public key is stored in your account in the region you create it. The Private key is immediately downloadable. In fact its the only time its available, so download and store it safely.
In the AWS Management Console change to the region you are working in. This is in the upper right hand drop down menu.
In the AWS Management Console choose Services then select EC2.
From the left-hand menu select Key Pairs. It’s half way down, in the Network & Security section.
Click Create Key Pair in the main panel and give your new key a name. Click Create.
Save the keypair to your local machine for easy access later. note: we will need this key to access the Cisco CSR router that is in our Simulated Datacenter VPC.
