 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) ...

In this blog post, we dive deep into the art of subnetting IPv4 addresses, a crucial skill for network administrators and engineers. We start with the fundamentals of subnetting, explaining how IP addresses are divided into network and host portions. The post includes a variety of practice questions, each accompanied by detailed explanations to help you master the concepts. Whether you're preparing for certification exams or just brushing up on your skills, this guide will provide you with the knowledge and confidence you need to tackle subnetting challenges. #Subnetting #IPv4 #Networking #IP Addressing #CCNA #Network Administration #IT_Certification #Practice Questions #NetworkEngineering #Subnetting #Explained (Solutions Provided at End) Question #1 What is the range of assignable IP addresses for a subnet containing an IP address of 172.16.1.10 /19? a. 172.16.0.1 – 172.16.31.254 b. 172.16.0.1 – 172.16.63.254 c. 172.16.0.0 – 172.16.31.255 d. 172.16.0...

MPLS TROUBLESHOOTING TIPS FOR CISCO AND JUNIPER #mpls #cisco #juniper #troubleshooting #huawei #copy #tutorial Basic MPLS Troubleshooting Tips 1. Verifying MPLS Configuration: Cisco: Use  show mpls interfaces  to verify that MPLS is enabled on the correct interfaces. Check  show mpls ldp neighbor  to ensure that Label Distribution Protocol (LDP) neighbors are discovered, and that the session is up. Juniper: Use  show mpls interface  to check MPLS status on interfaces. Utilize  show mpls ldp session  to confirm LDP neighbor sessions. 2. Checking Label Switch Paths (LSP): Cisco: Use  show mpls ldp bindings  to display local and remote label bindings. show mpls forwarding-table  helps to inspect the labels being forwarded and their corresponding next-hops. Juniper: Use  show mpls lsp extensive  to get detailed information about the LSPs. show route table mpls.0  to view the label-switched routes. 3. Ensuring Proper Route...
