Description
Specify the type of interface.
By default, the software chooses the correct interface type based on the type of physical interface. Therefore, you should never have to set the interface type. The exception to this is for NBMA interfaces, which default to an interface type of point-to-multipoint. To have these interfaces explicitly run in Nonbroadcast multiaccess (NBMA) mode, configure the nbma interface type, using the IP address of the local ATM interface.
In Junos OS Release 9.3 and later, a point-to-point interface can be an Ethernet interface without a subnet.
Default
The software chooses the correct interface type based on the type of physical interface.
