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 consider 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 neighbor establishment.
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
Configuring the P2MP network type for an interface
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
P2MP.
ospf network-type p2mp [ unicast ]
By default, the network type of an
interface depends on the link layer
protocol.
After you configure the OSPF
network type for an interface as
P2MP unicast, all packets are unicast
over the interface. The interface
cannot broadcast hello packets to
discover neighbors, so you must
manually specify the neighbors.
4. Return to system view. quit N/A
5. Enter OSPF view.

router-id | vpn-instance
