Configuring The Network Type Of An Ospf Interface; Setting An Nbma Neighbor - Huawei Quidway S3900 Series Operation Manual

Operation Manual – Routing Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
In addition, when configuring a broadcast network or NBMA network, you can also
specify DR priority for each interface to control the DR/BDR selection in the network.
Thus, the router with higher performance and reliability can be selected as a DR or
BDR.
4.5.1 Configuration Prerequisites
Before configuring the network type of an OSPF interface, perform the following
tasks:
Configuring the network layer address of the interface so that the adjacent node
is reachable at network layer
Performing basic OSPF configuration

4.5.2 Configuring the Network Type of an OSPF Interface

Table 4-4 Configure the network type of an OSPF interface
Enter system view
Enter interface view
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 whether
the adjacent router has the right to vote.
