Connection with legacy (non-sdwan) branches

When an organization migrates its existing WAN network to SD-WAN, installing SD-WAN equipment at some sites is not always possible. In such cases, migrated SD-WAN sites should be able to communicate with legacy branches over the underlay MPLS network.

LAB 2 - OMP Redistribution and Loop Prevention

This lesson will explore the most common use case when a dual-homed site has two WAN edge routers doing route redistribution between the Cisco Overlay Management Protocol (OMP) and any site-local routing protocol running on the service side.

LAB 9 - Per VPN topologies

In Cisco SD-WAN, per VPN topologies actually means manipulating the OMP routing in such a way that different service VPNs take different paths in the network. However, the overlay fabric is only one and has nothing to do with VPNs.

LAB 8 - Route Leaking

This lab lesson will explore another common use case of Cisco SD-WAN centralized control policies - exporting OMP routes between VPN routing tables.

LAB 7 - Service Chaining

In the context of Cisco SD-WAN, service chaining means injecting a network service such as a firewall into the path of specific data traffic in an automated manner.

LAB 1 - Service side redundancy using VRRP

One of the most commonly used redundancy options for the service side VPNs is to provide a resilient default gateway to hosts in a segment using the Virtual Router Redundancy Protocol(VRRP).

AAR alongside Data Policy

In the previous lesson about Application-aware (App-route) Policies, we have seen the tunnel selection process in different scenarios and policy actions.

Application-Aware Routing (App-route) Policy

An Application-Aware Routing (App-route) policy allows the SD-WAN fabric to monitor the quality of network paths in real-time and do SLA-driven routing across the best available transports.

Onboarding cEdge CSR1K

In this lesson, we will explore the process of onboarding cEdge routers (CSR1k) to the Cisco SD-WAN fabric using Enterprise CA and manual bootstrap configuration. This lesson complements our two previous articles on setting up a Cisco SD-WAN home lab for practicing.

LAB 6 - Mirror data traffic for analysis

A mirror instance sends a copy of certain data traffic to a specified destination for analysis.
