Cisco SD-WAN VPN Label concept is important to understand so we can analyse and troubleshoot network connectivity. I decided to discuss this topic in this section so that we can better understand the concept of service chaining, which will be discussed in the next few sections.
DetailsCisco SD-WAN Direct Internet Access enables sites to use the same Internet that is used for SD-WAN inter-site and internal transport connectivity. direct internet access and service publishing are implemented using NAT technology. These are the concepts that we will implement in this section.
DetailsCisco SD-WAN Route Leaking enables communication between different service VPNs. By default, no communication between different VRF or Service VPNs are allowed.
DetailsCisco SD-WAN QoS tools help us ensure the quality of our applications. One of the most important tools is queuing, which prioritizes delay-sensitive applications and guarantees bandwidth for application in proportion to their needs, so that junk or bulk traffic does not occupy the entire bandwidth.
DetailsCisco SD-WAN Traffic Shaping is another QoS feature for limiting traffic bandwidth. What is the difference between traffic policing and traffic shaping? Where traffic shaping or traffic policing is used? These are the questions which will be answered in this section.
DetailsCisco SD-WAN Bandwidth Policing makes it possible to limit bandwidth of specific data traffic. It is a data plane policy which can be implemented both in localized and centralized policy.
DetailsCisco SD-WAN application routing enables routers to route traffic based on their QoS requirements. You can determine QoS requirements such as delay, jitter, and loss for each application, and application-aware routing helps the router to route traffic in a path to meet QoS requirements. This feature is a data plane policy, meaning it doesn’t change routing table.
DetailsCisco SD-WAN Traffic Engineering, route traffic on a different path than routing table, without changing routing table, exactly like PBR (Policy Based Routing) in traditional Cisco routers.
DetailsCisco SD-WAN access list and application firewall is to filter data traffic as in non-SDN network environments. In this section we learn how to filter data traffic in network and transport layer and also application layer with the help of native cisco SD-WAN application firewall.
DetailsCisco SD-WAN non-direct internet access is the discussion of this section. non-direct internet access means tunnelling branch Internet traffic to a central site or datacenter for Internet access.
