Configuring an Interface on a Point-to-Multipoint Network

When you configure OSPFv2 on a nonbroadcast multiaccess (NBMA) network, such as a multipoint ATM or Frame Relay, OSPFv2 operates by default in point-to-multipoint mode. In this mode, OSPFv2 treats the network as a set of point-to-point links. Because there is no autodiscovery mechanism, each neighbor must be configured.

To configure OSPFv2 in point-to-multipoint mode, include the following statement:




interface interface-name {

neighbor address;
}

For a list of hierarchy levels at which you can configure this statement, see the statement summary section for this statement.

Specify the interface by IP address or interface name. For more information about interface names, see the JUNOS Network Interfaces Configuration Guide.

To configure multiple neighbors, include a neighbor statement for each neighbor.
