totally nssa - Totally nssa is an NSSA using 3 and 4 summary routes are not flooded into this type of
area. It is also possible to declare an area both totally stubby and not-so-stubby, which means that
the area will receive only the default route from area 0.0.0.0, but can also contain an autonomous
system boundary router (ASBR) that accepts external routing information and injects it into the
local area, and from the local area into area 0.0.0.0.
A router running OSPF sends hello packets to discover neighbors and elect a designated router. The
hello packet includes link state information and list of neighbors. OSPF is savvy with layer 2
topologies. If on a point-to-point link, OSPF knows it is sufficient, and the link stays up. If on a
broadcast link, the router waits for election before determining if the link is functional.
To define a dynamic routing configuration:
1. Select Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service
platforms or Access Points.
2. Select a target device (by double-clicking it) from amongst those displayed within the Device
Configuration screen.
Devices can also be selected directly from the Device Browser in the lower, left-hand, side of
the UI.
3. Select Profile Overrides from the Device menu to expand it into sub menu options.
4. Expand the Network menu and select OSPF.
The OSPF Settings tab displays by default, with additional Area Settings and Interface
Settings tabs available.
