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 Quagga daemon in Address Manager will configure advanced OSPF parameters.
To configure Anycast using OSPF on a DNS/DHCP Server:
- From the configuration drop-down menu, select a configuration.
- Select the Servers tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
- Under Servers, click a server name. The Details tab for the server opens.
- Click the server name menu and select Service Configuration. The Configure Remote Services page opens.
From the Service Type drop-down menu, select
Attention: If you have upgraded from Address Manager v3.7.x, you will receive the following warning message:
- This service has been set to Override. Any update to the service will overwrite the existing service configuration with the settings added in the user interface.
Modifying the current service configuration will disable the Service Configuration Override and overwrite the existing configuration file with the new values and settings.
Click Cancel to preserve the service configuration files maintained during the upgrade from Address Manager v3.7.x.
Under General Settings, set the following
- Enable Anycast Service—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.
- IPv4 Anycast
Address—enter a new IPv4 address (without netmask)
and click Add. The IPv4 address appears in
the list.Attention: Anycast OSPF on DNS/DHCP Server does not support IPv6 addresses.
- Add additional IPv4 addresses as needed.Note: IPv4 addresses must be unique.
- To delete an IPv4 address, select the address and click Remove.
- Add additional IPv4 addresses as needed.
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 (in seconds) 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 (in seconds) that the primary router contacts its peer/neighbor to indicate it is still active.
- Area Id—set the value of the OSPF area as either a 32-bit unsigned integer, or a 32-bit dotted decimal. For example, 1 or 0.0.0.1 (default). Do not enter an IPv4 address as the Area Id.
- Stub—select this check box to specify use of an OSPF subnet.
- Click Update.
