Procedure
Step 1 (Optional) Set the network type to NBMA.
The NBMA network must be fully meshed. Any two switches on the NBMA network must be
directly reachable. In most cases, however, this requirement cannot be met. To resolve this
problem, run specific commands to forcibly change the network type to NBMA. For details, see
Configuring Network Types for OSPF Interfaces.
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
ospf network-type nbma
The network type of the OSPF interface is set to NBMA.
Step 2 (Optional) Set the interval at which Hello packets for polling are sent on the NBMA network.
On the NBMA network, after the neighbor relationship becomes invalid, the switch sends Hello
packets at an interval defined in the polling mechanism.
1. Run:
ospf timer poll interval
The interval at which Hello packets for polling are sent by an NBMA interface is set.
The default value is 120, in seconds.
Step 3 Configure a neighboring switch on the NBMA network.
The interface with the network type of NBMA cannot broadcast Hello packets to discover
neighboring switches. Therefore, the IP address of a neighboring switch must be configured on
the interface and whether the neighboring switch can participate in DR election must be
determined on the interface.
1. Run:
quit
Exit from the interface view.
2. Run:
ospf [ process-id ]
The OSPF process view is displayed.
3. Run:
peer ip-address [ dr-priority priority ]
A neighboring switch is configured.
