Step Command

Remarks

4.

Configure a router priority for
the interface.

ospf dr-priority priority

Optional.
The default router priority is 1.

Configuring the OSPF network type for an interface as NBMA

After configuring the network type of an interface as NBMA, you need to make some special

configurations.
Because NBMA interfaces cannot find neighbors via broadcasting Hello packets, you need to specify

neighbors and their router priorities. (A router priority of 0 means the router does not have the DR election

right. A router priority greater than 0 means the router has the DR election right.)
To configure the OSPF network type for an Interface as NBMA:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter interface view.

interface interface-type
interface-number

N/A

3.

Configure the OSPF network

type for the interface as NBMA. ospf network-type nbma

By default, the network type of
an interface depends on the
link layer protocol.

4.

Configure a router priority for

the interface.

ospf dr-priority priority

Optional.
The default router priority is 1

5.

Exit to system view.

quit

N/A

6.

Enter OSPF view.

ospf [ process-id | router-id router-id
| vpn-instance vpn-instance-name ] * N/A

7.

Specify a neighbor and its

router priority.

peer ip-address [ cost value |
dr-priority dr-priority ]

N/A

NOTE:

The router priority configured with the ospf dr-priority command and the one configured with the peer
command have the following differences.

The former is for actual DR election.

The latter is to indicate 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 adjacency establishment.
