We are trying to set up NTP authentication on our cisco devices and our linux machines.
Our cisco router is the time source, it gets its time from another server in corporate without authentication.
What we need is for our cisco router to get its time from the corporate source WITHOUT authentication, but server time to our internal switches and linux servers WITH authentication.
I am attaching a VERY crude drawing to help explain what we need.
I need to know how to configure our router to get unauthenticated ntp time from a source, but authenticate anything it servers out. Does this make sense?
I am told by the Cisco guy that our router is a 6504
