Monitoring Open Shortest Path First (OSPF) routing domains

Edit online

You can determine whether there are events on any devices in your OSPF routing domains and OSPF areas. Use the OSPF Routing Domains network view to monitor OSPF routing domains and OSPF areas for events.

About this task

To monitor OSPF routing domains and OSPF areas, proceed as follows.

Procedure

  1. Click the Incident icon and select Network Availability > Network Views > Libraries.
  2. In the navigation tree on the left of the widget, click the + symbol to expand the OSPF Routing Domains node.
    For each top-level node, an event status icon to the right of the tree indicates the status of devices in that node.
  3. Determine the most severe event in each OSPF routing domain based on the associated event status icon.
  4. If an OSPF routing domain node has an event status icon of severity minor or higher, then select it.
    The network map displays devices in that routing domain and marks faulty devices with an event status icon.
  5. Check the status of the following devices within the network map.
    1. Area border routers (ABRs):
      These routers connect two or more OSPF areas and provide routing to other OSPF areas via the backbone network.
      ABRs are marked with the label ABR within the network map.
    2. Autonomous system border routers (ASBRs):
      These routers communicate with other networks using an IGP protocol.
      ASBRs are marked with the label ASBR within the network map.
    3. Designated routers (DRs) and backup designated routers (BDRs):
      DRs are OSPF router interfaces designated to provide a source for routing updates and so reduce the need to fully mesh connections when multi-access technologies, such as Ethernet, are used. A backup designated router (BDR) is always kept up to date to ease the transition should the primary DR fail.
      DRs are marked with the label DR within the network map. Backup DRs are marked with the label BDR within the network map.
    4. Type 2 LSAs:
      Generated for every transit network within an area. A transit network has at least two directly attached OSPF routers. Ethernet is an example of a Transit Network. A Type 2 LSA lists each of the attached routers that make up the transit network and is generated by the DR.
