Split Horizon, Route Poisoning and Holddown Explained. Split Horizon RIP as a distance vector protocol is also susceptible to routing loops (network problem which enables a data packet to continually be routed through the same routers over and over. The data packets continue to be routed within the network in an endless circle.). Split horizon is one of… Read More »
What is Router-on-a-stick Inter-VLAN Routing? Router-on-a-stick is a type of router configuration method in which a single physical interface manages traffic between multiple VLANs on a network. The router interface has to be configured to operate as a trunk link connected to a switch port (SW1) and enabled in trunk mode. The router receives VLAN-tagged traffic on the… Read More »

What Is Netflow? NetFlow is a network protocol developed by Cisco Systems for collecting IP traffic information and monitoring network flow. It’s widely used for network traffic analysis and forms the basis for a variety of network management and security applications. Here’s a brief overview of how NetFlow works: Data Collection: NetFlow-enabled devices, like routers and switches, keep… Read More »
What Is InterVLAN? We define inter-VLAN routing as a process of forwarding network traffic from one VLAN to another VLAN using a router or layer 3 device. A VLAN is a sub-group within a network, which partitions and isolates network traffic at the data link layer (Layer 2) of the OSI model. VLANs are used to segment networks for… Read More »
