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

Verification Commands

Understanding Methods in Java

  What is a Method? In Java, a method is a block of code that performs a specific task. Methods are used to define the behavior of objects created from a class. They encapsulate code that can be reused and invoked whenever needed, making programs more modular and manageable. Defining a Method A method consists of a method declaration and a method body. The method declaration provides the method's name, return type, and parameters, while the method body contains the code to be executed. Syntax: returnType methodName (parameters) { // method body } Example: public class Example { // Method to add two numbers public int add ( int a, int b) { return a + b; } public static void main (String[] args) { Example example = new Example (); int sum = example.add( 5 , 3 ); System.out.println( "Sum: " + sum); // Output: Sum: 8 } } Method Components Access Modifiers: Define the visibility of the method (e....

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-interf...
