I just performing a basic NTP Lab on GNS3.
I have three routers connected with a Switch on Vlan 1... I perform below commands. The clients clock are not synched
1- NTP SERVER:
Command #1#ntp maste
Command #2 ntp source fa 0/0
Command 3 ntp broadcast client ((on interface ))
2- NTP CLIENT:
Command# 1 ntp server 172.20.10.1
Command #2 ntp broadcast client (on interface )
Below are the output of show ntp status and sh ntp associations
NTP-S#sh ntp status
