Configuration Prerequisites; Configuring The Broadcast Network Type For An Interface; Configuring The Nbma Network Type For An Interface - HPE FlexNetwork HSR6800 Configuration Manual

Two broadcast-, NBMA-, P2MP-type interfaces can establish a neighbor relationship only when they
are on the same network segment.

Configuration prerequisites

Before you configure OSPF network types, complete the following tasks:
•
Configure IP addresses for interfaces so neighboring nodes can reach each other at network
layer.
•
Enable OSPF.

Configuring the NBMA network type for an interface

After you configure the network type as NBMA, you must specify neighbors and their router priorities
because NBMA interfaces cannot find neighbors by broadcasting hello packets.
A router priority of 0 means the neighbor does not have the right for DR election. A router priority
greater than 0 means the neighbor has the right for DR election.
The router priority configured with the ospf dr-priority command is for actual DR election. The
priority configured with the peer command indicates whether a neighbor has the election right or not.
If you configure the router priority for a neighbor as 0, the local router will assume the neighbor has
no election right, and thus send no hello packets to this neighbor. However, if the local router is the
DR or BDR, it still sends hello packets to the neighbor with priority 0 for neighborship establishment.
