The app-profile assigned to the aa-sub-id affects both stats and control of the policy. App-profiles are assigned to the transit AA subscribers either explicitly when the transit-aa-sub is created, or by default (when not specified) according to a default app-profile configured in a transit-ip-policy or transit-prefix-policy. This allows transit AA subscribers to be treated with a different default app-profile than the app-profile (default or specified) set against the parent aa sub. The number of AA subscriber stats used per ISA is proportional to the number of AA subscribers including transit subscribers subs are added.
ASO policy override is supported for static transit subs.
