NTP not updating
Posted on 2007-11-14
I have a cisco router with a public IP and i want it to server as an NTP server on my network
I have configured NTP on my cisco router but it looks like it's not updating so i need some help
//I have the following to tell my router to broadcast NTP on GE0/1 that is connected to my LAN
ip address 192.168.115.101 255.255.255.252
//I have the following for NTP configuration
ntp source GigabitEthernet0/2 --This is the interface connected to internet with a public IP
ntp server 188.8.131.52
ntp server 184.108.40.206
ntp server 220.127.116.11
//The clock is not sync

I don't know what's wrong with my configuration
How can i check that the public NTP server i'm using is correctly broadcasting time ?
Can i force my router to update the clock to see if it's working ?
