2.shall i give two core routers loop back ip as NTP server prefer?..(I have configured NTP settings in Core Router)
3.when i am giving in Switch# sh ntp associations
address ref clock st when poll reach delay offset disp
~127.127.7.1 127.127.7.1 7 5 64 377 0.0 0.00 0.0
10.175.135.12 .GPS. 1 26d 64 0 24.0 21259. 16000.
+~10.234.173.38 10.175.135.12 2 22 64 377 4.0 8.75 0.7
*~10.234.173.37 10.175.135.12 2 21 64 377 -0.0 14.27 0.4
* master (synced), # master (unsynced), + selected, - candidate, ~ configured
Customer is asking why you are giving same reference clock for the two routers?Can you change this into two Server IP?..
How i can change that ip?
What i have to do?

Hi Senthil,
Reference clock here is the local switch which is acting as ntp server for other clients in your network, so it is showing as assoicted with the following ip address with self as ref clock.
You can create another ntp server in your network as a backup for primary.
Hope to Help !!
