Release Information

Statement introduced in Junos OS Release 10.1.

Support for the [edit ... family pppoe] hierarchies introduced in Junos OS Release 11.2.

Description

Prevent the activation of another dynamic PPPoE logical interface on the same underlying interface when a dynamic PPPoE logical interface for a client with the same media access control (MAC) address is already active on that interface. Duplicate protection is disabled by default. Enabling duplicate protection has no effect on dynamic PPPoE logical interfaces that are already active.

Note: The [edit ... family pppoe] hierarchies are supported only on MX Series routers with MPCs.
