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 sensetive 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 acitivity 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.

ipsec configuration



In this tutorial we will Learn  how to  configure verify and troubleshoot LACP (Link Aggregation or Ether Channel). Actually Link Aggregation or Ether Channel is a technology very similar to PAgP which allows two or more than two physical ports to combine and provide a new third single logical port which results in high availability and increased bandwidth. In below topology diagram you can see two switches switch0 and switch1 having ports fa0/1 and fa0/2.Using LACP we can bind these two ports to form a single logical port.

In this tutorial we will learn about PAGP.We will learn how to configure PAGP and how to verify and troubleshoot it after configuration. But before that we must know what PAGP is.PAgP is actually a Cisco Proprietary Protocol which is known as Port Aggregation Protocol which is used to combine two or more physical ports in to a single logical port or you can say it as a EtherChannel.

backup route lab

In this lab we will learn how to configure backup route configuration in packet tracer.This is an example lab showing backup route configuration betwenn router0 and Router1.


extended acl lab

Here in this lab we will learn how to block or allow certain services binded on port.In other way you can that how to block or allow certain port or certain services using extended access-list in cisco packet tracer.This is an example lab showing how to block a certain port and how to allow a certain port using extended ACL.In this lab i am going to allow web services port say port number 80 and going to block FTP services say PORT 22.
