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:

  1. From the configuration drop-down menu, select a configuration.
  2. 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.
  3. Under Servers, click the name of a BDDS. The Details tab for the server opens.
  4. Click the server name menu and select Service Configuration.
  5. From the Service Type drop-down menu, select Anycast.
  6. Under General Settings, set the following parameters:
    • 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 doesn't 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.
  7. 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'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—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.
  8. Click Update.
