Scenario #4 - Advanced Route Leaking
This lesson will demonstrate a route-leaking scenario that is not common in real-world deployments but is very instructive. It will show you how VPNs and LABELs work in the context of route leaking.
Scenario #2 - Last-resort-circuit for a single app
This lesson will demonstrate a scenario with several requirements that we will solve using an Application-aware Routing policy in combination with a few additional SD-WAN features.
OMP TLOC-Action
In the last lesson, we saw the differences between traditional routing protocols and overlay routing with OMP. We have seen that OMP does not reroute around failures in the overlay by default.
Scenario #3 - AAR in point-to-multipoint topologies
App-route policies can only select local colors according to a pre-defined SLA class. However, what happens in point-to-multipoint topologies where one local color establishes tunnels to multiple remote colors?
Understanding OMP Routing
This lesson will demonstrate the major differences between the Overlay Management Protocol (OMP) and traditional routing protocols.
Scenario #1 - Preferred DC in a dual-DC design
This lesson will show a scenario with several tasks that we will solve using different SD-WAN techniques. Along the way, we will learn how to approach different topology and traffic engineering requirements.
Understanding VPNs and LABELs
In this lesson, we will explore the concept of labels in Cisco SD-WAN. Labels are an essential part of the solution and are used for segmentation, route leaking, and service chaining.
Cisco SD-WAN Main Principles
In this lesson, we will explore the main principles that the Cisco Software-defined Wide-area Network (SD-WAN) architecture has adopted to solve the inefficiencies of the traditional WAN.
LAB 10 - Dynamic On-demand Tunnels
Dynamic On-demand Tunnels is a Cisco SD-WAN feature that triggers the establishment of an IPsec overlay tunnel between two sites only when there is traffic between the two WAN edger routers. After the flow of direct traffic stops and the pre-defined idle-timer expires, the tunnel is placed in an inactive state.
Hierarchical SD-WAN
Hierarchical SD-WAN is a design option of the Cisco SD-WAN overlay that provides the capability to separate the WAN network into independent regions. Similarly to the OSPF area logic, a hierarchical SD-WAN network must always have a core region, called region 0, that connects all other access regions.
