Spectracom SecureSync User Manual

Please note that SecureSync utilizes the OSPF (Open Shortest Path First) and BGP (Border Gate-
way Protocol).
O S P F P r o t o c o l E X A M P L E :
If an active SecureSync NTP server has removed itself as an available time source from the Anycast-
capable network, the OSPF router will send a request for replacement to the next nearest NTP server,
serving under the same NTPoverAnycast address.
As soon as the first SecureSync server obtains a valid reference again, it will make itself available to
the OSPF router, which will then use it as a time source again, based on the principle of shortest path
available.
