 Cisco SD-WAN revolutionizes network management by decoupling the control and management planes from WAN edge routers, centralizing them in software-based controllers. This architectural shift improves security, availability, and scalability, making Cisco SD-WAN a preferred choice for managing large and distributed networks. In this blog post, we’ll explore the roles of vEdge routers and the SD-WAN controllers, namely vSmart, vManage, and vBond, each of which interacts with WAN edge devices in unique ways to ensure secure, streamlined, and reliable control connections. Control Connections and Security Protocols Each vEdge router establishes secure control connections to SD-WAN controllers using DTLS or TLS protocols. DTLS, which operates over UDP, is the default protocol due to its efficiency and speed, while TLS, running over TCP, provides slightly enhanced reliability. These protocols create secured tunnels that shield the control plane protocols (such as OMP, NETCONF, and SNMP) ...

  TROUBLESHOOTING BGP/MPLS ON CISCO AND JUNIPER DEVICES Mastering the Basics: Troubleshooting BGP/MPLS on Cisco and Juniper Devices Introduction: In the intricate world of networking, BGP (Border Gateway Protocol) and MPLS (Multi-Protocol Label Switching) are fundamental technologies that enable efficient, scalable, and robust communication across vast and diverse infrastructures. Understanding how to troubleshoot these protocols in Cisco and Juniper devices is essential for maintaining a smooth operational network. Today, we’ll dive into some practical tips to help you navigate common issues with these technologies. Understanding BGP/MPLS Basics: BGP : As the backbone of the internet, BGP makes routing decisions based on paths, network policies, or rule sets, which allows it to be very flexible and robust. However, it can also be complex and challenging to troubleshoot. MPLS : MPLS enhances the flow of traffic on a network by making data forwarding decisions based on short path la...

Types of Links  that can be created on a Network Switch Video Tutorial link given at end ACCESS LINKS Access Links are the most common type of links on any VLAN switch. All network hosts connect to the switch's Access Links in order to gain access to the local network. These links are your ordinary ports found on every switch, but configured in a special way, so you are able to plug a computer into them and access your network. knowledge streams blog spot dot com free knowledge blog. download free source codes for python and java and other free stuff. We must note that the 'Access Link' term describes a configured port - this means that the ports above can be configured as the second type of VLAN links - Trunk Links. What we are showing here is what's usually configured as an Access Link port in 95% of all switches. Depending on your needs, you might require to configure the first port (top left corner) as a Trunk Link, in which case, it is obviously...
