OSPF State

An OSPF enabled controller or service platform sends hello packets to discover neighbors and elect a designated router for dynamic links. The hello packet includes link state data periodically updated on all OSPF members. The controller tracks link state information to help assess the health of the OSPF dynamic route.

To view OSPF state statistics:

1. Select the Statistics menu from the Web UI.
2. Expand the RF Domain node.
3. Select a Wireless Controller.
4. Select OSPF from the left-hand side of the UI.
5. Select the OSPF State tab.
   The Statistics > Controller > OSPF > OSPF State screen displays.

   

   

   This screen provides the following information:

   OSPF state	Displays the OSPF link state amongst neighbors within the OSPF topology. Link state information is maintained in a LSDB (link-state database) which is a tree image of the entire network topology. Identical copies of the LSDB are periodically updated through flooding on all OSPF supported nodes. Flooding is the part of the OSPF protocol that distributes and synchronizes the link-state database between OSPF routers.
   OSPF ignore state count	Lists the number of times state requests have been ignored between the controller and its peers within this OSPF supported broadcast domain.
   OSPF ignore state monitor timeout	Displays the timeout that, when exceeded, prohibits the controller from detecting changes to the OSPF link state.
   OSPF max ignore state count	Displays whether an OSPF state timeout is being ignored and not utilized in the transmission of state update requests amongst neighbors within the OSPF topology.
   OSPF max routes	States the maximum number of routes negotiated amongst neighbors within the OSPF topology.
   OSPF routes received	Lists the routes received and negotiated amongst neighbors within the OSPF topology.
