Configure NBMA Interface Neighbors

Configure NBMA neighbors so that the interface can participate in designated router election. All neighbors that you manually insert on the Neighbors tab are NBMA neighbors.

Before you begin

Enable OSPF globally.
Ensure that the interface uses an IP address.
Ensure that the interface type is NBMA.
Change the VRF instance as required to configure OSPF on a specific VRF instance. The VRF must have an RP trigger of OSPF. Not all parameters are configurable on non-default VRFs.

Procedure

In the navigation pane, expand Configuration > IP.
Select OSPF.
Select the Neighbors tab.
Select Insert.
Enter the IP address and priority for the first neighbor.
Select Insert.
Add all required neighbors.
Select Apply.

Neighbors Field Descriptions

Use the data in the following table to use the Neighbors tab.


Name	Description
NbrIpAddr	Specifies the neighbor IP address.
AddressLessIndex	Indicates addressed and addressless interfaces. This value is 0 on an interface with an IP address. On addressless interfaces, the corresponding value of ifIndex in the Internet standard management information base (MIB).
NbrRtrId	Specifies the router ID of the neighboring router. The router ID has the same format as an IP address but identifies the router independent of its IP address.
Options	Specifies the bit mask that corresponds to the neighbor options parameter.
Priority	Specifies the priority.
State	Specifies the OSPF interface state.
Events	Specifies the number of state changes or error events that occur between the OSPF router and the neighbor router.
Retransmission Queue Length	Specifies the number of elapsed seconds between advertising retransmissions of the same packet to a neighbor.
ospfNbmaNbrPermanence	Indicates whether the neighbor is a manually configured NBMA neighbor; permanent indicates it is an NBMA neighbor.
HelloSuppressed	Indicates whether hello packets to a neighbor are suppressed.
RestartHelperStatus	Specifies whether the router is acting as a graceful restart helper for the neighbor.
RestartHelperAge	Specifies the remaining time in the current OSPF graceful restart interval, if the router is acting as a restart helper for the neighbor.
RestartHelperExitReason	Specifies the outcome of the last attempt at acting as a graceful restart helper for the neighbor.
