Spectracom NetClock 9489 - Configuring NTP over Anycast (OSPF Ipv4)

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 the IP Version you will be running Anycast service for. The
options are IPv4, IPv6, or both.
6.
Configure the Anycast Address to be used.
7.
Select the port to associate the Anycast service with (depending on the option card con
figuration 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.
8.
Click Submit.
Note: IMPORTANT: For Anycast to function, NetClock 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 Ver
sion 2 (IPv4). Determine the OSPF area.
2.
In the NetClock 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 con
figuration 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 mul
tiple 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 page59).
13.
Next, specify the maximum TFOM Setting (Time Figure of Merit), and the Holdover
Timeout value. These two parameters determine NetClock's accuracy "tolerance win
dow": A small window will cause NetClock to deliver a more accurate time window, but
