Description (partial)

NTP packet does not reach NTP server due to packet drop by TTL Limit expiry in case of IPv4 and Hop Limit expiry in case of IPv6.

NTP client is configured in the XR devices with an unicast IP address for NTP server and this condition happens when that NTP server is far away with TTL/Hop Limit over 30.
