About Configuring Dynamic Interfaces over Static ATM

518
example, the following command specifies ATM 1483 subinterface 20 on slot 5, adapter
0, port 0 of an E320 router.
host1(config)#interface atm 5/0/0.20
For more information about supported interface types and specifiers on E Series routers,
see Interface Types and Specifiers in JunosE Command Reference Guide.

To create dynamic interfaces over ATM, you create the static layers of the interface first,
and then configure them to support a dynamic interface by means of autodetection.
Figure 46 on page 518 shows an example of the interface stack for a dynamic IP over
ATM 1483 interface.
Figure 46: Configuring an ATM 1483 Interface to Support Dynamic
Interfaces
On receipt of a packet, the router creates all dynamic layers above the ATM 1483 layer,
starting with the lowest dynamic layer. For example, in the case of a dynamic PPPoE
interface, the router creates the PPPoE interface first, then the PPP interface, and then
the IP interface.
If any layer of the dynamic portion of the interface column fails to be created, then the
interface creation fails and the connection is denied. All dynamic layers above the ATM
1483 subinterface are destroyed, starting with the highest dynamic layer.
When you configure a dynamic interface, you must assign (or create and assign) a profile
to the interface. Profile creation and assignment topics are discussed in depth in
"Configuring a Dynamic Interface from a Profile" on page 559.
