Setting An Nbma Neighbor; Setting The Dr Priority On An Ospf Interface - H3C S7500 Series Operation Manual

Operation Manual – Routing Protocol
H3C S7500 Series Ethernet Switches
Configure the network
type of the OSPF
interface
Note:
After an interface has been configured with a new network type, the original
network type of the interface is removed automatically.
Note that, neighboring relationship can be established between two interfaces
configured as broadcast, NBMA, or P2MP only if the interfaces are on the same
network segment.

4.5.3 Setting an NBMA Neighbor

Some special configurations need to be done on an NBMA network. Since an NBMA
interface cannot discover the adjacent router by broadcasting Hello packets, you must
manually specify the IP address of the adjacent router for the interface and specify
whether the adjacent router has the right to vote.
Follow these steps to set an NBMA neighbor:
Enter system view
Enter OSPF view
Set an NBMA neighbor

4.5.4 Setting the DR Priority on an OSPF Interface

You can control the DR/BDR election on a broadcast or NBMA network by configuring
the DR priorities of interfaces.
Follow these steps to set the DR priority on an OSPF interface:
To do...
ospf network-type
{ broadcast | nbma |
p2mp | p2p }
To do...
system-view
ospf [ process-id
[ router-id router-id ] ]
peer ip-address
[ dr-priority dr-priority ]
Use the command...

Required
By default, the network
type of an interface
depends on the physical
interface.
