Address Manager Administration Guide

Product name
BlueCat Address Manager

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 a server name. 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, (default), or
    • Stub—select this check box to specify use of an OSPF subnet.
  8. Click Update.
