By default, OSPF assumes that the interface is attached to a broadcast network.
You can use the BCC or Site Manager to specify another network type.
Using the BCC
To change the interface type, go to an OSPF interface prompt (for example,
box;
eth 2/2; ip/2.2.2.2/255.255.0.0; ospf
) and enter:
type
<
interface_type>
interface_type
is one of the following types (Table 6-2):
Table 6-2. OSPF Interface Types
Type Description
broadcast Default value for the interface if it is not point-to-point. Use if the network
is a broadcast LAN, such as Ethernet.
nbma Choose nbma (nonbroadcast multi-access) if the network is a
nonbroadcast network, such as ATM.
pointtopoint Default value for the interface if it is point-to-point. If the interface is
point-to-point, this setting is the only option available.
ietf Choose ietf if the network is a point-to-multipoint network. It is
recommended that you use this network type rather than the Nortel
Networks proprietary point-to-multipoint network.
pmp Choose pmp (point-to-multipoint) to use the Nortel Networks proprietary
point-to-multipoint solution.
passive Choose passive to configure an interface that OSPF cannot use to form
neighbor relationships. OSPF cannot accept Hello messages or send
advertisements on the passive interface.
