Configuration (Cfg.)
The source context will facilitate the HA service(s), and the Gi interface(s) to the FA(s).The source context will also be
configured with AAA interface(s) and to provide Home AAA functionality for subscriber sessions. The destination
contexts will each be configured to facilitate PDN interfaces. In addition, because each of the destination contexts can
be outsourced to different domains, they will also be configured with AAA interface(s) and to provide AAA
functionality for that domain.
In addition to the source and destination contexts, there are additional system-level AAA parameters that must be
configured.
