OSPF Configuration

Configuring OSPF 


Step 1: Enter Configuration Mode
Router> enable
Router# configure terminal

Step 2: Enable OSPF
Enable OSPF with a process ID. The process ID is locally significant and can be any number.
Router(config)#router ospf <process-Id>

Step 3: Set the OSPF Router ID
Setting a unique OSPF Router ID is optional but recommended for stability and troubleshooting. The Router ID should be a unique IPv4 address within the OSPF domain.

Router(config-router)# router-id <router-id>

Step 4: Define Networks to Include in OSPF
Specify which networks will participate in OSPF and their corresponding areas. Ensure the areas match across all routers in the OSPF domain.

Router(config-router)# network <network-address> <wildcard-mask> area <area-id>

Step 5: Save the configuration
Router(config-router)#exit
Router(config)#do write / do wr

Java Overview

What is Java?  Java is a popular programming language for developing web, mobile, and desktop applications. It is a high-level and object-oriented programming language. It is platform-independent. It required the Java Virtual Machine(JVM) to run the Java code. Java is similar to C/C++. Application of Java Mobile Application Desktop Application Web Application Embedded System Smart Card Payment System Games History of Java Java's history dates back to the early 1990s when a group of researchers at Sun Microsystems led by James Gosling started a "green project". The goal of this project was to create a portable home-appliance software that could run on embedded processor chips. Initially, the team planned to use C++ programming language for this project. However, they encountered portability issues with C++ and decided to develop a new programming language from scratch. This led to the creation of the Oak programming language, named after an oak tree outside Gosling's o

Configuring Static NAT for Any Network Scenario

Introduction Network Address Translation (NAT) is a fundamental technique used in networking to translate private IP addresses to public IP addresses and vice versa. Static NAT is a method where a specific private IP address is mapped to a specific public IP address.  Configuration Steps Router Configuration Enable NAT Service Router(config)# ip nat inside source static [inside-local] [inside-global] Replace [inside-local] with the private IP address to be translated. Replace [inside-global] with the public IP address to translate to. Configure Interfaces Router(config)# interface [inside-interface] Router(config-if)# ip address [inside-ip-address] [subnet-mask] Router(config-if)# ip nat inside Router(config-if)# no shutdown Router(config-if)# exit Router(config)# interface [outside-interface] Router(config-if)# ip address [outside-ip-address] [subnet-mask] Router(config-if)# ip nat outside Router(config-if)# no shutdown Router(config-if)# exit Replace [inside-interface]
