Setup the OSPF Area .
Select the OSPF Port to associate the Anycast service with (depending on the option card
configuration of your unit, there may be only ETH0 available), and click Submit .
Next, specify the maximum
Timeout value. These two parameters determine SecureSync's accuracy "tolerance win-
dow": A small window will cause SecureSync to deliver a more accurate time window, but
also will cause it quicker to withdraw from the Anycast server pool, i.e. declare itself an
invalid reference. (To find out more about TFOM, see "Oscillator Disciplining Setup" on
page 192.)
Navigate to Management > Disciplining , and click the GEAR icon in the top-right corner of
the Status panel.
Set the value Maximum TFOM for Sync to 4 (this will make SecureSync to go out of sync
if the phase error is greater than 1μs).
Set the value for Holdover Timeout to 10 s, to allow SecureSync to exit holdover quickly.
Leave the Phase Error Limit at 0, and do not check any of the checkboxes (or, for more
information, see "Oscillator Disciplining" on page 188).
Click Submit .
