Configuring Catalyst Switches

When you power on a new purchased Switch for the first time, it runs a series of Power-On Self Tests (POSTs) operations. A  POST is designed to verify the basic operations of the network interfaces, memory, and CPU. The following post results are visible when we...

Configuring EIGRP

Consider the topology given below – The initial IP configuration table is given below: Devices Interface IP address Router1 Se0/0/0 192.168.10.1 Router1 Fa0/0 10.0.0.1 Router2 Se0/0/0 192.168.10.2 Router2 Fa0/0 20.0.0.1 Switch1 N/A N/A Switch1 N/A N/A PC1 Fa0 10.0.0.2...

Types of Spanning Tree Protocol

There are the following types of Spanning Tree Protocol – 1. Common Spanning Tree (802.1D) A Common Spanning Tree (802.1D) standard is developed by IEEE which elects only one Root Bridge for the whole topology. 802.1D uses blocking, listening, learning, and forwarding...

Spanning Tree Protocol (STP)

Spanning Tree Protocol (STP) is a Data link layer (layer 2) protocol that is used to discover and maintain a valid loop-free path for the switched network. It is also used to analyze the port speed in the topology and determine which port should be open and which port...

Switching

A switch is a network device which is used to connect multiple devices (routers, computers) inside the LAN (Local Area Network). It operates at Data Link Layer (Layer 2) of the OSI reference model. Functions of a switch A list of functions of switches is given below:...

VLAN Basics

VLAN stands for Virtual Local Area Network. It is a logical group of networking devices that allows a single extended LAN to be partitioned into several separate LANs. The important feature of VLANs is that it is possible to change the logical topology without...

Configuring IP Routing in Our Network

There are 3 types of IP routing that we can configure in our network. Default RoutingStatic RoutingDynamic Routing Default Routing Default Routing is used to configure unknown destination networks.It is used on stub networks. Stub networks are those networks which...

EIGRP Basics

EIGRP stands for Enhanced Interior Gateway Routing Protocol. It is also called as the Hybrid routing protocol. It contains the features of both distance vector and link-state routing protocols. Characteristics of EIGRP There are the following characteristics of EIGRP:...

Static Routing

Static Routing Static Routing is the process in which static routes are manually added to the routing table through the direct configuration. Static routing is configured in the global configuration mode using syntax: Router(config)#ip route...
