ppp-options (Dynamic PPP)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 9.5.

Support at the [edit dynamic-profiles profile-name interfaces "$junos-interface-ifd-name" unit “$junos-interface-unit”] hierarchy level introduced in Junos OS Release 12.2.

lcp-connection-update option added in Junos OS Release 20.2R1.

Description

Configure PPP-specific interface properties in a dynamic profile.

Note

PPP options can also be configured in a group profile with the ppp-options (L2TP) statement. The following behavior determines the interaction between the PPP options configured in a group profile and the PPP options configured in a dynamic profile:

  • When PPP options are configured only in the group profile, the group profile options are applied to the subscriber.

  • When PPP options are configured in both a group profile and a dynamic profile, the dynamic profile configuration takes complete precedence over the group profile when the dynamic profile includes one or more of the PPP options that can be configured in the group profile. Complete precedence means that there is no merging of options between the profiles. The group profile is applied to the subscriber only when the dynamic profile does not include any PPP option available in the group profile.

Options

lcp-connection-updateEnable PPP to act on a Connection-Status-Message VSA (26–218) received by authd in either a RADIUS Access-Accept message or a CoA message. PPP conveys the contents of the VSA in an LCP Connection-Update-Request message to the remote peer, such as a home gateway. This action requires the following to be true:
  • At least the first address family has been successfully negotiated and the session is active.

  • The router LCP is in the Opened state.

Otherwise PPP takes no action on the VSA. If you do not enable the lcp-connection-update option, PPP processes the notification from authd, but takes no action.

Default: Disabled
