interface-type interface-number.subnumber: Interface type and interface number. 
The interface-number argument is the primary interface number, and the 
subnumber argument is the sub-interface number, ranging from 0 to 1023.

p2mp: Configures the type of a WAN sub-interface to be point-to-multipoint.

p2p: Configures the type of a WAN sub-interface to be point-to-point.

Use the interface interface-type interface-number.subnumber [ p2mp | p2p ] 
command to create a WAN sub-interface and enter WAN sub-interface view.

Use the undo interface command to remove the specified sub-interface.

Currently, point-to-multipoint or point-to-point sub-interfaces can be configured 
for ATM interfaces, frame relay interfaces or X.25 interfaces. By default, 
point-to-multipoint sub-interfaces are created.

A Layer 3 Ethernet interface can accommodate 1 to 4,096 sub-interfaces.
