Use the no form of these commands to remove the configured parameter value or return to the
default value.

Configuring OSPF Network Types

OSPF classifies different media into the three types of networks by default:
•
•
•
You can also configure network interfaces as either a broadcast or an NBMA network and as point-to
point or point-to-multipoint, regardless of the default media type.

Configuring OSPF for Nonbroadcast Networks

Because many routers might be attached to an OSPF network, a designated router is selected for the
network. If broadcast capability is not configured in the network, the designated router selection requires
special configuration parameters. You need to configure these parameters only for devices that are
eligible to become the designated router or backup designated router (in other words, routers with a
nonzero router priority value).
OL-9639-07
Broadcast networks (Ethernet, Token Ring, and FDDI)
Nonbroadcast multiaccess (NBMA) networks (Switched Multimegabit Data Service [SMDS],
Frame Relay, and X.25)
Point-to-point networks (High-Level Data Link Control [HDLC], PPP)
Purpose
(Optional) Enable MDS authentication.
• keyid—An identifier from 1 to 255.
• key—An alphanumeric password of up to 16 bytes.
(Optional) Block flooding of OSPF LSA packets to the interface. By
default, OSPF floods new LSAs over all interfaces in the same area,
except the interface on which the LSA arrives.
Return to privileged EXEC mode.
Display OSPF-related interface information.
Display NSF awareness status of neighbor switch. The output
matches one of these examples:
Options is 0x52
•
LLS Options is 0x1 (LR)
When both of these lines appear, the neighbor switch is NSF
aware.
Options is 0x42—This means the neighbor switch is not NSF
•
aware.
(Optional) Save your entries in the configuration file.
