When you boot the router, it issues an ntpdate request, which polls a network server to determine the local date and time. You need to configure a server that the router uses to determine the time when the router boots. Otherwise, NTP will not be able to synchronize to a time server if the server’s time appears to be very far off of the local router’s time.
To configure the NTP boot server, include the boot-server statement at the [edit system ntp] hierarchy level:
- [edit system ntp]
-
boot-server address;
Specify the address of the network server. You must specify an address, not a hostname.
