2.15.12.5 Configuring Anycast via NTP Expert Mode
Advanced Anycast configuration is possible via the NTP Expert Mode (see also "NTP
Expert Mode" on page126), which allows you to write directly into the Anycast con-
figuration files (zebra.conf; ospfd.conf; ospf6d.conf and bgpd.conf).
The zebra.conf file is required for both IPv4, and IPv6 Anycast. The ospfd.conf file is
required for IPv4 OSPF only, the ospf6d.conf file is required for IPv6 OSPF only, and the
bgpd.conf file has multiprotocol functionality, hence it can be used for both IPv4, and
IPv6 Anycast.
Caution: Expert Mode should only be utilized by advanced users, as incor-
rectly altering the Anycast files can cause Anycast to stop working.
Caution: Any configurations made in Expert Mode will be lost as soon as
Expert Mode is disabled.
1.
To access Expert Mode, navigate to MANAGEMENT > NTP Setup.
2.
Enable the switch for Expert Mode in the panel NTP Services.
3.
Once it is enabled, click NTP Anycast in the Actions Panel. The Expert mode win-
dow will appear, with a separate tab for each of the three configuration files.
4.
To enable OSPF IPv4 Anycast, check Enable under the OSPF tab. To enable OSPF
IPv6 Anycast, check Enable under the OSPF6 tab. To enable BGP Anycast, check
Enable under the BGP tab. Then click Submit.
When the NTP Anycast Expert Mode window is opened, the files displayed are the con-
figuration files in their current states. If no configuration was done outside of Expert Mode,
these will be the factory default files. If Anycast configuration was already done from the
Web UI, you will be able to edit the existing Anycast setup.
