NTP SOURCE

ntp source
Overview Use this command to configure an IPv4 or an IPv6 address for the NTP source
interface. This command defines the socket used for NTP messages, and only
applies to NTP client behavior.
Use the no variant of this command to remove the configured IPv4 or IPv6 address
from the NTP source interface.
ntp source <source-address>
Syntax
no ntp source
Default An IP address is selected based on the most appropriate egress interface used to
reach the NTP peer if a configured NTP client source IP address is unavailable or is
an invalid IP address.
Mode Global Configuration
Usage Adding an IPv4 or an IPv6 address allows you to select which source interface NTP
uses for peering. The IPv4 or IPv6 address configured using this command is
matched to the interface.
When selecting a source IP address to use for NTP messages to the peer, if the
configured NTP client source IP address is unavailable then default behavior will
apply, and an alternative source IP address is automatically selected. This IP
address is based on the most appropriate egress interface used to reach the NTP
peer. The configured NTP client source IP may be unavailable if the interface is
down, or an invalid IP address is configured that does not reside on the device.
Note that this command only applies to NTP client behavior. The egress interface
that the NTP messages use to reach the NTP server determined by the
ntp server
