Configure OSPF via Device Manager
From the Configure menu, choose OSPF.
Table 90 - OSPF Fields
Field Description
OSPF Instances—Add OSPF instances to the OSPF table. To customize the default settings for an instance, see
page 342.
Instance ID Type a unique value to identify internally the OSPF routing process.
Valid values: 1…65535
Router ID Type the IP address of the router that is associated with the OSPF instance.
Area/Networks—Configure the area properties and networks for the OSPF instance.
OSPF ID Choose the OSPF routing process ID.
Area ID Type an identifier of the area to associate with the OSPF address range. You can use either a decimal value or an IP address. If you intend to
associate areas with IP subnets, you can specify a subnet address as the value.
Area Type Click an area type and specify related parameters:
• Normal—Normal areas can be either standard areas or transit (backbone) areas. Standard areas can accept intra-area, inter-area, and external
routes. The backbone area is the central area to which all other areas in OSPF connect.
• Stub—Stub areas do not receive information about external routes.
– Summary—Allows sending link-state advertisements
(LSAs) into the stub network.
• NSSA—Not-so-stubby-areas are an extension of OSPF stub areas. However, an NSSA can import external routes into the OSPF routing domain.
Every router within the same area must agree that the area is an NSSA.
– Redistribution—Allows routes redistribution.
– Summary—Allows sending LSAs into an NSSA network.
– Default Information Originate—Enable on an area border router (ABR) to allow the importing of type 7 LSAs into an NSSA network.
Network Address Type one or multiple interfaces to be associated with a specific OSPF area.
IMPORTANT: Any individual interface can be attached to only one area. If the address ranges specified for different areas overlap, the system
adopts the first area in the network list and ignore the subsequent overlapping portions. In general, we recommend that you configure address
ranges that do not overlap to avoid inadvertent conflicts.
Network Mask Choose an IP-address-type mask.
Authentication Click the authentication type for the area:
• No Authentication
• Password
• MD5
The authentication type must be the same for all routers and access servers in an area.
Default Cost Type a value to specify the cost of sending a packet on an interface.
Valid values: 1…65535
Default: 1
