EIGRP MD5 Authentication

Written by Rene Molenaar on . Posted in EIGRP

Scenario:

Ben and Jerry are running their business from the north pole and have an icy request for you. They would like you to setup EIGRP (Enhanced Interior Gateway Routing Protocol) and make sure that all network updates are secure by enabling authentication...don't get cold fingers on this one, time to warm up the routers!

Goal:

  • All IP addresses have been preconfigured for you.
  • Both routers has a loopback0 interface:
    Ben: 1.1.1.1 /24
    Jerry: 2.2.2.2 /24
  • Configure the correct date and time for both routers. Just configure today's date/time.
  • Configure EIGRP AS 12 on both routers, advertise all networks.
  • Ensure you have an adjancency and routing information is exchanged.
  • Enable MD5 authentication for EIGRP AS 12 with the following parameters:
    Key Chain: GNS3VAULT
    Key-ID 1: password chunky
    Key-ID 2: password monkey
  • Key1 should be valid from today until 15 minutes later from the moment you configure it.
  • Key2 should be valid from today and will never expire.
  • Ensure routing information is still exchanged between both routers.

It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the protocols for CCNA.
