Data Plane Encryption
Cisco SD-WAN utilizes in order to scale better and more efficiently. Most traditional IPsec environments use Internet Key Exchange (IKE) to handle the key exchange between IPsec peers.
TLOCs and NAT
Cisco SD-WAN solution is designed to run over any kind of WAN transport that is available to the WAN edge devices including all different public networks such as Broadband, 4G/5G, LTE, Business Internet, and so on. This implies that the overlay fabric should be able to form through all flavors of Network Address Translations that these public networks utilize.
LAB 4 - Traffic Engineering - TLOC Preference
In this lab, we are going to make some traffic engineering by modifying the TLOC preference of one of the WAN edge routers at the hub site.
Direct Internet Access (DIA)
Cisco SD-WAN Direct Internet Access is a solution that improves the user experience for SaaS applications at remote sites by eliminating the performance degradations related to backhauling Internet traffic to central data centers.
LAB 3 - Hub-and-Spoke - Enabling spoke-to-spoke communication
Recap of the previous lab
In lab 2, we have created a Centralized Policy named CENTRALIZED-CONTROL-POLICY-V2 using the vManage GUI.
Interconnecting Multiple Clouds
I think every network engineer has already seen that applications are moved to the cloud on a massive scale in recent years. Some apps are even developed and deployed directly in the cloud. These are known as Cloud-native applications or "born in the cloud".
