Through Nexus Dashboard you have created and deployed your Site1 Greenfield VXLAN EVPN fabric and performed a level of verification by checking the deployment status that Nexus Dashboard reports. Now, you're going to use your Terminal to connect to some devices in your Site1 fabric to issue show commands for verification of the configuration deployed by Nexus Dashboard. Additionally, using the Linux servers connected to your Site1-L1 and Site1-L2, you will perform data plane verification by checking connectivity to your Anycast Gateway and checking inter-VXLAN routing between your two servers.
Verification will start with your Site1-S1 spine switch.
The first device you will verify is your Site1-S1 switch. Login to your Site1-S1 switch using the copy command below and paste into your Terminal. When prompted, the password is cisco.123 .
If prompted to accept the RSA key fingerprint like below, type or copy yes then input the password above.
The authenticity of host '10.3.5.11 (10.3.5.11)' can't be established.
RSA key fingerprint is SHA256:xneE+2XnZozaXwC/FgeYMRKJ4UhZV4iZD6QCD1u7gi8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '10.3.5.11' (RSA) to the list of known hosts.
