Statement introduced in Junos OS Release 13.1.
For IPv4 and IPv6 dual-stack PPP subscribers, enables on-demand allocation and de-allocation of an IPv4 address after initial PPP authentication for a subscriber who does not have an existing IPv4 address.
Configuration changes take effect as follows:
When you change this setting for a dynamic PPP interface (at the [edit dynamic-profiles] hierarchy level), the change takes effect only for new subscriber logins.
When you change this setting for a static PPP interface (at the [edit interfaces pp0] hierarchy level, the subscribers on the interface are logged out.
When you change this setting globally (at the [edit protocols ppp-service] hierarchy level), the change takes effect only for new subscriber logins.
If you enable on-demand allocation at both the interface and global levels, the global configuration takes precedence and changes take effect for new subscriber logins.
This functionality is disabled by default.
