Configuring the NBMA network type for an interface
After you configure the network type as NBMA, you must specify neighbors and their router priorities because NBMA interfaces cannot find neighbors by broadcasting hello packets.
To configure the NBMA 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 NBMA. | ospf network-type nbma | By default, the network type of an interface depends on the link layer protocol. |
4. (Optional.) Configure a router priority for the interface. | ospf dr-priority priority | The default setting is 1. The router priority configured with this command is for DR election. |
5. Return 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 [ dr-priority dr-priority ] | By default, no neighbor is specified. The priority configured with this 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 determines the neighbor has no election right, and does not send hello packets to this neighbor. However, if the local router is the DR or BDR, it still sends hello packets to the neighbor for neighbor relationship establishment. |
