Hi,
Though i searched on internet i couldn't find any tip about the effect of ntp signalling load on cpu of routers and network bandwidth.We have a network containing 1350 units of routers ranging from 1700,2500,2600,3600s,to 4 X 7200 and 3X7500.For ntp configuration we want to choose the method of delivering time choosing the right servers,peers.
If it does not take to much cpu so i will make 3 units of 7500 router as ntp server but if it is problem for this much network so i will choose 80 routers over the country as servers...bandwidh is critical,cpu is critical .sure this will couse configuration difficulty..i am waiting for your valuable ideas...
