In the first post I shared with you my code to calculate tunnel numbers in Cisco SD-WAN. I’m a beginner in Python so I thought it would be a great learning experience to have someone experienced in Python, such as
Using Python to Calculate Cisco SD-WAN Tunnel Numbers – Part 1
When using Cisco SD-WAN on IOS-XE, it uses tunnel interfaces to configure parameters of the implementation. There is a mapping between what interface the tunnel is sourcing from and the name of the tunnel interface. For example, if the tunnel
