OSPF Settings

In the OSPF Settings window, configure the OSPF settings.

OSPF Setting

Description

Cost

The cost given to the default stub or not-so-stubby-area (NSSA) route. Enter a value from 0 to 15. Lower cost routes are preferable.

Hello Interval

Interval that must elapse between the transmission of hello packets on the interface. The range is 10 to 120 seconds; the default is 10 seconds.

Dead Time

Number of seconds the PortMaster waits after ceasing to receive a neighboring router’s hello packets and before identifying the remote router as unreachable. The range is 40 to 1200 seconds; the default is 40 seconds.

Interface

From the pulldown list, select one of the following:

nbma
(Optional) Configures the port as the interface for a nonbroadcast multiaccess (NBMA) Frame Relay network that has full mesh connectivity. All routers on the Frame Relay running OSPF.

Setting this value specifies a designated router on the Frame Relay network, and reduces overall OSPF traffic overhead.

point-to-multipoint
(Optional) Configures the port as the interface for a point-to-multipoint Frame Relay network. Use this setting when the Frame Relay network has partial mesh connectivity, or when all OSPF speakers on the network cannot communicate with each other.

Setting this value configures the partially meshed Frame Relay network as a series of point-to-point interfaces.

wan-as-stub-ptmp
(Optional) Configures the port as the interface for a point-to-multipoint WAN-as-stub Frame Relay network. This setting works similarly to point-to-multipoint but is used in cases when the PortMaster must interoperate with other-vendor equipment that implements a variant of point-to-multipoint.

Setting this value designates the Frame Relay network as a stub network in the router link state advertisement (LSA), as opposed to the standard host route.
