14.
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).
15.
Set the value for Holdover Timeout to 10s, to allow SecureSync to exit holdover
quickly.
16.
Leave the Phase Error Limit at 0, and do not check any of the checkboxes (or, for
more information, see "Configuring the Oscillator" on page230).
2.15.12.4 Configuring NTP over Anycast (BGP)
To configure NTP over Anycast, using BGP (Border Gateway Protocol):
1.
Confirm that your existing network infrastructure is Anycast capable, and uses BGP.
Determine the network specifics, such as your Autonomous System (AS) number,
Neighbor’s address and Neighbor’s AS number.
2.
In the SecureSync Web UI, navigate to MANAGEMENT > Network > NTP Setup.
3.
In the Actions Panel, click NTP over Anycast.
4.
In the NTP Anycast window, select the General tab.
5.
On the General tab, select your desired IP Version. This selection automatically com-
municates with the BGP tab and displays the neighbor address field based on your
needs.
6.
Select the port to associate the Anycast service with (depending on the option card
configuration of your unit, there may be only ETH0 available). If you desire IPv6 func-
tionality, you must also select the IPv6 port address since there may be multiple IPv6
addresses on a single port.
7.
In the NTP Anycast window, navigate to the BGP tab.
8.
On the BGP tab, check Enable.
9.
Input your AS number.
10.
Input the neighbor's address.
11.
Input the neighbor's AS number.
12.
Click Submit.
13.
Select the port address to associate the Anycast service with (because there may be
multiple addresses on a single port), and click Submit. If no addresses appear, an IP
address must be added to the port.
14.
Next, specify the maximum TFOM Setting (Time Figure of Merit), and the Holdover
Timeout value. These two parameters determine SecureSync's accuracy "tolerance
window": A small window will cause SecureSync to deliver a more accurate time win-
dow, but also will cause it to quickly withdraw from the Anycast server pool, i.e.
declare itself an invalid reference. (For more information about TFOM, see
