Redistribution between EIGRP and Static Routing Protocol

Here in this lab i will show how to configure redistribution between static routing and eigrp.For that configuration i have taken 3 router having total 4 networks.here middle router is configured with both EIGRP and Static Route.This is an static route and eigrp redistribution example lab shown using cisco packet tracer.


If you are preparing for ccnp routing exam you can study below redistribution labs:


Route Redistribution between EIGRP and OSPF.

Route Redistribution between RIP and EIGRP.

Route Redistribution between RIP and OSPF.

bgp configuration lab using cisco packet tracer


In this article I am going to show you how to configure bgp step by step.This is a bgp configuration example lab showing bgp configuration using cisco packet tracer.I will show you how to configure bgp routing protocols on cisco router using three router.This is an example lab showing bgp configuration.Here in This Lab I have taken  3 AS they are 1,71 and 79 respectively

BGP neighbors can be of two types:


  • IBGP neighbors – when two neighbors are in the same AS(Autonomous System);

  • EBGP neighbors – when two neighbors belong to different AS(Autonomous System).

This is a Route Redistribution between OSPF and EIGRP configuration Lab. In this tutorial we will learn how to configure Route Redistribution between OSPF and EIGRP using Cisco Packet Tracer.I have made a step wise tutorial showing redistribution process between EIGRP and OSPF and also performed Network connection Testing after Configuration.If you are preparing for CCNP Certification this lab will help you score and learn Route distribution Questions.

Redistribution is done to enable communication between routers running different protocols.

For Example here in this lab you can see two different protocols EIGRP and OSPF.

You can also Learn:
Route Redistribution between RIP and OSPF Routing domain
Route Redistribution between RIP and EIGRP

Route Redistribution configuration lab between RIP and OSPF Routing domain.This lab is to show route redistribution between RIP routing and OSPF Routing.So if you are preparing for ccnp certification then this tutorial is for you.I have mentioned step wise notes with proper documentation to configure Route Redistribution between RIP and OSPF routing protocol.

Redistribution is done when you want to take routes learn from one routing protocol and put them in another Routing protocol.

here in This Lab we are putting the RIP Route in to OSPF Route and OSPF route in to RIP Route.

In this lab we will see how to configure route redistribution between RIP and EIGRP. We use Route Distribution because Route Redistribution allows routes from one routing protocol to be advertised into another routing protocol.It helps network admin to make it possible to communicate between different routing protocols.It is also possible to redistribute from one routing protocol to the same routing protocol, such as between two separate OSPF domains (distinguished by unique process ID’s). Static routes and connected interfaces can be redistributed into a routing protocol as well.  While configuring route redistribution Routing metrics are a key consideration.

Learn how to configure IPSEC site to site vpn on cisco router using cisco Packet Tracer.As we all know IPsec provides secure transmission of sensitive data over unprotected networks like internet.So what actually IPsec does is it acts at the network layer which means its working in network layer of TCP/IP model and protecting sensitive data and authenticate IP packets only between participating IPsec devices like cisco routers. here in this IPSEC Example lab Router0 and Router1 is is participating in IPsec peers.So in this activity or in this lab i will configure these two routers to support a site to site IPsec VPN for traffic flowing from their respective LANs.

While configuring this lab I consider that everyone who is going to configure this lab must know how to assign ip address on router interfaces and if you don’t you can read my articles on  How to assign ip address on Router interfaces..

In this tutorial we will learn how to configure and use vpn on routers.We will learn to create a vpn tunnel between routers for safe communication.

In this tutorial we will learn how to configure router as a terminal server or an access server.Here in below diagram Router0 is working as a terminal server or you can say an access server.

So what this actually mean?

It means if a client seating on PC0 will try to login to router r1, r2,r3,r4 or r5 he/she cannot be able to access these routers directly,he/she must have to go through Router0 which is an access server.

In previous lab we have learnt how to configure OSPF clear text authentication,and now in this lab we will learn how to configure OSPF MD5 authentication which more secure than clear text authentication.Configuring OSPF MD5 authentication is very similar to configuring clear-text authentication. (more…)

If you have done your CCNA,you already familiar with the term OSPF and you also know how to configure it,but if you are new to networking you can learn about ospf along with it’s configuration from my blog.Today here i am going to discuss about how to configure ospf authentication on routers.OSPF can authenticate every OSPF message. This is usually done to prevent a rogue router from injecting false routing information and therefore causing a Denial-of-Service attack.

Two types of authentication method that can be used are:

1. clear text authentication clear text passwords are used,which is not more secure.

2. MD5 authenticationMD5 authentication is used. This type of authentication of more secure.

IMPORTANT NOTEwith OSPF authentication turned on, routers must pass the authentication process in order to become OSPF neighbors.

Here in this Lab we will learn how to configure clear text authentication method to secure ospf messages. (more…)
