About This Chapter
The information provided here on interface types, configuration procedures, and configuration
examples can help you make full use of logical interfaces.
16.1 Introduction to Logical Interfaces
Logical interfaces do not exist physically. They are manually configured for data exchange.
16.2 Features of the AR1200 Logical Interfaces
This section describes the applicable environment of logical interfaces.
16.3 Configuring a Sub-interface
By configuring sub-interfaces, you can enable the AR1200 to communicate with multiple peer
devices.
16.4 Configuring a Loopback Interface
Loopback interfaces always remain in the Up state once created and execute the loopback
function.
16.5 Configuring a NULL Interface
All the packets sent to NULL interfaces are discarded.
16.6 Configuring an MP Group Interface
A Multilink PPP (MP) group interface is used to perform MP binding to increase link bandwidth.
16.7 Configuring a Dialer Interface
By binding a physical interface (such as a serial, BRI, or asynchronous interface) to a dialer
interface, you can enable the physical interface to inherit the configuration of the dialer interface.
16.8 Configuring Virtual-Ethernet Interfaces
Virtual-Ethernet (VE) interfaces allow one data link protocol to transmit data of other link layer
protocols. This section describes the applicable environment and basic configurations of VE
interfaces.
16.9 Configuring Virtual-Template Interfaces
Virtual-Template (VT) interfaces allow PPP links to transmit data of other link layer protocols.
This section describes the applicable environment and basic configurations of VT interfaces.
