Can someone please explain how does the knob 'targeted-distribution' works in Juniper MX routers.
We created aggregated Ethernet (AE) links on our Juniper MX router acting as BNG. However , after creating bundle links and terminate subscribers on it , it was revealed that subscribers are getting more bandwidth than what was being policed. JTAC suggested to apply knob 'targeted-distribution' under dynamic profile to address the issue. After applying the knob , the problem got solved.
I have tried to learn from Juniper documentation but here is what i understand.
As per my understanding , this knob distributes the dynamic interfaces (created for BNG subscribers) among the member links in a bundle. Some subscribers may be on one member link while other subscribers on other member link. The policier which is being pushed by AAA/SRC against any subscriber will then rate limit traffic on that member link at which subscriber resides because without this knob , subscriber traffic will be hashed on all member links in a bundle and rate limit will be active for each individual member link in a bundle , hence all subscribers getting more speed than their profile on BNG.
Please correct me if I am missing something or I am wrong altogether. And How does it differs from 'shared-bandwidth-policer' knob
