If you require a dynamic routing protocol for a large-scale network, you can use
Anycast with OSPF for routing IP packets within a single autonomous system. The FRRouting
daemon in Address Manager will configure advanced OSPF parameters.
To configure Anycast using OSPF on a DNS/DHCP Server:Attention: Anycast OSPF is not supported for IPv6-only environments.
Enabling Anycast OSPF with an IPv4 Anycast address for an IPv6-only DNS/DHCP
server is an invalid configuration.
-
Select the Servers tab in the sidebar, then select
Servers.
-
Select the name of a server.
-
Select the Services tab.
-
Under Core services, locate the Anycast service
panel and select Edit service.
-
Set the following parameters:
- Enabled—select this check box to enable
Anycast service; deselect this check box to disable Anycast
service.
- Protocol—select OSPF. Different
fields become available depending on the type of protocol that you
select.
- Anycast IPv4
Addresses—enter a new IPv4 address (without netmask)
and click Add (+). The IPv4 address appears
in the list.
-
Set the optional authentication parameters:
- Authenticate—select this option to
enable authentication. When selected, the
Password field becomes available.
- Password—enter a password for
authentication.
- Dead interval—set the length of time that the
peer/neighbor router will maintain a route to the primary router in the
absence of hello messages.
- Hello interval—set the length of time that the
primary router contacts its peer/neighbor to indicate it's still
active.
- Area ID—enter the value of the OSPF area as
either a 32-bit unsigned integer, or a 32-bit dotted decimal. For
example, 1, 0.0.0.1 (default), or 192.168.1.1.
- Stub area—select this check box to specify use of
an OSPF subnet.
- Enable authentication key—select this option to
encrypt OSPF routing information. When selected, the
Authentication Key field becomes
available.
- Authentication key—enter the authentication key
used for OSPF. The authentication key is used to compute the MD5 hash
that is used to authenticate OSPF packets. The authentication key is
cleartext and can be a maximum of 16 characters.

Select Save.
