Which of the below is true when talking about Performance Routing? But Why? Performance Routing allows the router to make intelligent routing decisions based on WAN link performance, which can help with more efficient utilization of available memory and CPU processing cycles. It is also well suited for routing within both LANs as well as … Read more
Which command is used to save the cisco router configuration? Explanation To save the Cisco router configuration, you can use the “wr mem” command or the “copy running-config startup-config” command. The “wr mem” command writes the current running configuration to the router’s non-volatile memory (NVRAM), where the startup configuration is stored. The “copy running-config startup-config” … Read more
What is SDWAN? SDWAN is a software-defined networking technology that allows for the creation of virtualized network overlays. SDWAN provides a number of benefits over traditional networking approaches, including improved flexibility, scalability, and performance. SDWAN is typically implemented as an overlay network, which means that it sits on top of an existing physical network infrastructure. … Read more
What are Virtual Routing And Forwarding? Virtual Routing and Forwarding (VRF) is a technology that enables the creation of multiple virtual Layer 3 routing and forwarding instances on a single physical router. Each VRF instance is essentially a separate virtual router, with its own unique routing table, forwarding table, and other data structures. VRF allows … Read more
What is CEF? Cisco Express Forwarding (CEF) is a Layer 3 switching technology that offers high performance, low latency, and Scalability. It is the successor to Cisco’s Distributed Forwarding technology. CEF is used in Campus Networks and Data Centers to provide optimal forwarding of traffic. CEF uses a central Adjacency Table which contains next-hop information … Read more
