I am here to share my knowledge and experience in the field of networking with the goal being - "The more you share, the more you learn." The previous book in this series, The Packet Guide to Core Network Protocols, covered the IPv4 protocols, masking, and devices that are part of every network.Now it’s time to take on the routing and switching for the network. "IP Networking: Part 2 ‐Routing and Switching" Advertised Presentation Scope: IP Networking Fundamentals for Broadcast Engineers is an intensive instructor - lead webinar series focused on major IP networking topics. If you have clear understanding of packet vs circuit switching then you can understand this concept easily. Difference between Routing and Switching. The L2 data (for ethernet) present in the packet header includes Destination MAC, Source MAC, VLAN etc. Devices in the same layer 2 segment do not need routing to reach local peers. According to basic definition of a router, it is a device which performs packet switching or Layer-3 forwarding and this layer-3 routing forwarding were typically performed in software or by means of programing algorithms. Routing allows computers to link through the internet, thus allowing for information sharing between different networking systems. The fundamental concept for Switching is it works at Layer 2 (L2) and Routing works at Layer 3 (L3) of the networking stack. For switching to happen L2 lookup is necessary. Whereas switching creates a single network made up of individual computers, routing connects entire networks to each other. On 24 February 2020, the current CCIE Routing and Switching v5.0 … It continues toward the goal of implementing protocols that are best suited for your design. switching vs forwarding vs routing | difference between switching,forwarding,routing. Routing and Switching Strategies. Traditional switching operates at layer 2 of the OSI model, where packets are sent to a specific switch port based on destination MAC addresses. Switching protocols; Routing protocols; Chapter 7 A model for decision making. Migration from CCIE Routing and Switching to CCIE Enterprise Infrastructure. Routing operates at layer 3, where packets are sent to a specific next-hop IP address, based on destination IP address. The chapter begins with a recap of choices made in the last chapter about placement of switches and routers. I am Rashmi Bhardwaj. Chapter 1. Switching • The networking device which performs switching is known as switch. The CCNP – Routing and Switching: The Cisco Certified Network Professional – Routing and Switching is considered as an intermediate-level certification that would be validating the learners’ expertise and experience in networking with Cisco products. Conclusion When regarding to choose between a layer 3 switch vs router, you need to understand the business requirement before make your decision: in general, it is proper to get a router when most of the time your device does the routing, otherwise, a layer 3 switch may fit better when you need more ports, better network performance and VLAN segmentation. For routing to happen L3 lookup is necessary. This page compares switching vs forwarding vs routing and mentions difference between switching, forwarding and routing. Take faster routing decisions: Take more time for complicated routing decisions: NAT (Network Address Translation) Routers can perform NAT: Switches cannot perform NAT: Faster: In a different network environment (MAN/ WAN), a router is faster than an L3 switch.
