Note: NTP over Anycast is not compatible with DHCP, as it is designed to
be used with static addresses only.
Note: IMPORTANT: For Anycast to function, SecureSync must be in sync
to a valid reference, or to itself.
2.15.12.2 Configuring NTP over Anycast (OSPF IPv4)
To setup the NTP over Anycast functionality, using OSPF IPv4:
1.
Confirm that your existing network infrastructure is Anycast capable, and uses
OSPF Version 2 (IPv4). Determine the OSPF area.
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 IPv4 as the IP Version.
6.
Configure the Anycast Address to be used.
7.
Select the port to associate the Anycast service with (depending on the option card
configuration of your unit, there may be only ETH0 available).
8.
In the NTP Anycast window, navigate to the OSPF tab.
9.
On the OSPF tab, check Enable.
10.
Setup the OSPF area.
11.
Click Submit.
12.
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 (see "Network Ports" on page60).
13.
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 "Con-
figuring the Oscillator" on page230.)
Navigate to Management > Disciplining, and click the GEAR icon in the top-right
corner of the Status panel.
