NTP (Network Time Protocol)

Scenario:

You are the owner of a Swiss watch factory. Time is everything to you and the same applies to your network. You want to make sure that your complete network is synchronized and up-to-date. Now get going since time is money!

Goal:

• All IP addresses have been preconfigured for you.
• EIGRP has been configured for full connectivity.
• Configure router Planck and Atomic to be NTP Masters, use stratum 10.
• Make sure router Planck and Atomic synchronize with each other.
• Router Julian has to check router Planck and Atomic for NTP updates, it has to prefer router Atomic.
• Configure router Julian so it broadcasts NTP packets on its FastEthernet 1/0 interface.
• Configure router Century so it configures itself using the NTP broadcast packets from router Julian.
• Configure router Planck to send NTP packets to multicast address 239.5.5.5.
• Configure router Millenium to configure itself using the NTP multicast packets.
