I have Core Router, Distribution and Access router.
Core Router will get clock from Internet
Distribution Routers will associate with Core Router for NTP clock and
access Routers will associate Distribution Router for NTP Clock.
I have configured Core router as NTP master with command "ntp master 2" and "ntp server x.x.x.x"(to rx clock from Internet)
"ntp peer <ip address of Core Router>
"ntp server <ip address of distribution router>"
Is the method I followed is correct. Do I have to change any thing to achieve this. Because access routers clock is not in sync. I doubt whether i am conceptually wrong
