In this article, we will discuss evolving packet-switching methods for example Process Switching, Fast Switching and Cisco Proprietary Cisco Express Forwarding (CEF) Packet Switching is the method of moving a packet from a router’s input interface to an output interface. When Cisco routers were first developed and deployed, only one way existed to switch the […]
What will we learn in this article? How Load Balancing Works on a Cisco router when CEF is disabled. How Load Balancing Works on a Cisco router when CEF is enabled. How the load is distributed among various equal cost path interfaces of a router. So, let’s continue.. Load balancing is a standard functionality of […]
Segment Routing (SR) allows a flexible definition of end-to-end paths within IGP topologies by encoding paths as sequences of topological subpaths called Segments. These segments are advertised by the link-state routing protocols (IS-IS and OSPF). Prefix segments represent an ECMP-aware shortest path to a prefix (or a node), as per the state of the IGP […]
In this article we will understand IPv4 Class B subnetting. Let’s begin by understanding basic definitions. Definition of IP Address: An IP address is a 32 bit number that logically defines a host. IP address assigned to a LAN card or a device interface can change based on network admin’s requirement. Definition of Subnet Mask: […]
