AAA option sets to authorize and configure subscribers per routing instance to support username stripping

You can include one or more of the following statements at the new [edit access aaa-options aaa-options-name] hierarchy level to define a set of AAA options for a subscriber or set of subscribers that username stripping is applied to: 

•  access-profile profile-name-Specify the name of the access profile that includes the username stripping configuration. 
•  aaa-context aaa-context-name-Specify the logical-system:routing-instance that the subscriber session uses for AAA (RADIUS) interactions like authenticating and accounting. 
•  subscriber-context subscriber-context-name-Specify the logical-system:routing-instance in which the subscriber interface is placed. 

 Use the aaa-options aaa-options-name statement at the [edit dynamic-profiles profile-name interfaces pp0 unit $junos-interface-unit ppp-options] hierarchy level to apply the attributes to PPP subscribers tunneled from the LAC to the LNS inline service interface. 

 Alternatively, use the aaa-options aaa-options-name statement at the [edit access group-profile profile-name ppp-options] hierarchy level to apply the attributes to PPP subscribers tunneled from LACs that are members of the user group. 

Usernames are examined and modified according to the subscriber and AAA contexts specified in the option set. In the event of a conflict between option sets configured in both a group profile and a dynamic profile, the dynamic profile takes precedence.
