• 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 the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Expand the Network menu and select Dynamic Routing.
