In the topology above we’re going to setup NTP. The ‘Internet’ router will become an NTP server and R6/R4 will be the clients.
Server:
We’re setting the ‘server’ as master with stratum 1.
Clients:
96.76.43.142 is the IP assigned to ‘Internet’. Shortly after a ‘show ntp status’ should produce the client being synchronized with the NTP server.
Authentication:
