OmniSwitch CLI Reference Guide

Creates a static neighbor on a non-broadcast interface.

ip ospf neighbor neighbor_id {eligible | non-eligible}

no ip ospf neighbor neighbor_id

A unique 32-bit IP address identical to the neighbor’s interface address.

Sets this router as eligible to be the DR.

Sets this router as not eligible to be the DR.

• NBMA (Non Broadcast Multi Access), PMP (Point-to-Multipoint), and P2P (Point-to-Point) OSPF 

non-broadcast modes are supported over Ethernet interfaces (broadcast media).

• Neighboring routers on non-broadcast OSPF networks must be statically configured, because lack of 

OSPF multicast capabilities prevents using normal OSPF Hello protocol discovery.

• In the case of NBMA interface the static neighbor eligibility for becoming a DR can be configured 

while it is not necessary for point-to-multipoint and point-to-point interfaces.

• An interface connected to this neighbor must also be configured as a non-broadcast interface, which 

can be either point-to-multipoint or point-to-point, by using the 

• For the correct working of an OSPF NBMA network, a fully meshed network is mandatory. Also, the 

neighbor eligibility configuration for a router on every other router should match the routers interface 
priority configuration.
