OSPF with DHCP configuration

OSPF (Open Shortest Path First) is a router protocol used to find the best path for packets as they pass through a set of connected networks.

OSPF is designated by the Internet Engineering Task Force (IETF) as one of several Interior Gateway Protocols. The OSPF routing protocol has largely replaced the older Routing Information Protocol (RIP) in corporate networks.

OSPF with DHCP configuration project done by ICSS student Swastick Raj Chatterjee. Here discussed the process below of the configuration.

Before starting the configuration Let’s discuss about OSPF

OSPF is a link state protocol. It depends on IP network. OSPF uses Dijkstra algorithm (an algorithm for finding the shortest paths between nodes in a graph) and interface bandwidth to decide interface cost. OSPF router creates neighbor and it uses hello messages to create and maintain the neighborhood. It is exchanges special messages known as Link State Advertisement (LSA) instead of exchanging routes directly.

STEPS ARE GIVEN BELOW to make out this configuration

Draw the model as per the requirements of the configuration in step 1

We will create 4 types of configuration for each router in 2nd step. 4 types of configuration are mentioned below:

1^st type of configuration is fast Ethernet port configuration;

2^nd type of configuration is IP DHCP configuration;

3^rd type of configuration is serial port configuration; and

4^th type of configuration is OSPF configuration.

Now Let’s start with the 1^st router which is known as ROUTER 0

Router 0

Now check whether the DHCP request successfully came or not in the first router;

Now come to the second router configuration which is known as ROUTER1

Router 1

Check whether the DHCP request successfully came or not to make sure for the corrections of the configuration.

Third router configuration described below by the snapshot. Third router known as ROUTER 2.

Router 2

Now check whether the DHCP request has came or not.

In the last step of the configuration I have shown by the snapshot of packet sending from one laptop to another laptop and the packet sending result should be in a successful mode.

User can confirm that the configuration has created in a right way by showing the successful packet sending confirmation message.
