How to Configure OSPF DR and BDR (Manipulating OSPF DR & BDR Election)

Leave a Comment / Configuration / /

Unlike point-to-point OSPF network, where OSPF routers exchange hello messages using the OSPF hello protocol to establish and maintain neighbor relationships, a multi-access network with three or more OSPF routers needs to elect an OSPF-designated router (DR) and a backup-designated router (BDR) in order to establish and maintain neighbor relationships. The DR and BDR are […]

How to Configure OSPF Passive Interface on Cisco Router

Leave a Comment / Configuration / /

Whenever we advertise networks on a router in the OSPF configuration mode, the OSPF route advertisement will be enabled on all the interfaces of the router. However, it is good practice to disable the advertisement on interfaces connecting to networks that are not part of the autonomous system or interfaces that are idle. Disabling the

How to Configure OSPF Backbone Area | How to Configure OSPF Area 0

Leave a Comment / Configuration / /

OSPF is a widely used dynamic routing protocol. It is an open standard protocol, meaning that any router will support it. It uses a link-state algorithm to dynamically learn the route to every subnet existing in a single autonomous system. In a multi-area OSPF network, the backbone area (Area 0) obtains the summarized route from

How to Configure OSPF Multi-Area

Leave a Comment / Configuration / /

OSPF is a widely used and widely advertised routing protocol. It is an open standard, meaning that any router will support it. It is an interior gateway protocol, meaning it is designed to work within a single autonomous system. It is also a link-state dynamic routing protocol. As with other routing protocols, the goal of

How to Configure Default Route on Cisco Router

Leave a Comment / Configuration / /

In any network, routers play the role of forwarding traffic from one network to another. They make decisions about where to send data packets based on routing tables, which contain information about known networks and the best paths to reach them. One important concept in routing is the default route, also known as the gateway

How To Configure EIGRP on a Cisco Router

Leave a Comment / Configuration / /

EIGRP is a dynamic routing protocol that combines the characteristics of both distance vector and link-state algorithms to discover routes and build routing tables. It is an advanced distance vector protocol that has link-state-like features. It is a Cisco proprietary protocol. EIGRP is an internal gateway protocol, meaning it is designed to be used with

Static Route Configuration in Cisco Router

Leave a Comment / Configuration / /

Static route configuration is a fundamental method of building routing tables in networking. It involves manually adding network addresses leading to other networks to a router. This enables the router to be able to determine the best path for forwarding packets. Static Route Configuration Methods Static route configuration can be implemented using either the Command

How to Configure HSRP on Cisco Router

Leave a Comment / Configuration / /

In networking, ensuring both high availability and Internet connectivity are paramount. One of the key technologies used to achieve high availability in Cisco Network is the Hot Standby Router Protocol (HSRP). Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol that provides high network availability by allowing two or more router to serve

How to Configure PAgP EtherChannel in Cisco Packet Tracer

Leave a Comment / Configuration / /

In Cisco networking, EtherChannel offers a method to bundle multiple physical Ethernet links into a single logical link, providing increased bandwidth and redundancy. One of the key aspects of configuring EtherChannel is selecting the appropriate mode, with one option being the Port Aggregation Protocol (PAgP), a Cisco proprietary protocol. This blog post will guide you

How to Configure Static Etherchannel in Cisco Packet Tracer

Leave a Comment / Configuration / /

EtherChannel, also known as Link Aggregation, allows network administrators to group multiple physical Ethernet links into a single logical link. This aggregation increases bandwidth, provides fault tolerance, and enhances load balancing across the bundled links. In this guide, we’ll walk through configuring a static EtherChannel using the manual mode (ON mode) on Cisco Catalyst switches
