Configure the device to use its loopback or OOB management interface address as the source address when originating NTP traffic.
Review the configuration and verify the loopback interface address is used as the source address when originating NTP traffic. If the device is managed from an OOB management network, the OOB interface must be used instead. The configuration should look similar as shown in the following example:
interface loopback 0
ip address 10.10.2.1 255.255.255.255
…
ntp server 129.237.32.2
ntp server 142.181.31.6
ntp source Loopback0
Note: IOS allows multiple loopback interfaces to be defined.
