First of all thank you for the prompt reply Aleksandar :) Your update in March 2018 was clear. I 've read it and I followed the link to this document.   I asked the question because until 5.3.4 there was a specific/different recommended release for BNG than the recommended release for other functionality. Given that this document doesn't include any specific comments about BNG, I wanted to clarify that 6.4.2 is recommended for all functionalities (BNG included) and there isn't any different recommendation for BNG.   Thanks again, Dimitris ...

Hi, Aleksandar, Hope you are doing good.   I have a couple of questions and I would appreciate your help: Is 6.4.2 the recommended version for BNG/RSP-440-SE or do we need to follow the recommendation in BNG deployment scale guidelines on ASR9000 ( The XR release 5.3.4 is the Cisco suggested release for all BNG deployments. )? Which is the recommended upgrade path for BNG/RSP-440-SE in terms of hardware (route processor)? Best Regards, Dimitris ... View more

Hey Xander,   Quick as always :) Thanks!   So, if I am not mistaken, we don't expect any scaling issues in the following setup, even if we apply the policy to all 64K sessions, right? 2 x A9K-RSP440-SE 1 x A9K-MOD80-SE 64K LC DS PPPoE sessions policy-map PARENT-POLICY class class-default service-policy CHILD-POLICY shape average 20 mbps ! end-policy-map ! policy-map CHILD-POLICY class CHILD-CLASS bandwidth remaining percent 30 ! class class-default ! end-policy-map   Regards, Dimitris ...

Hi Aleksandar, Xander,   Hope you are both doing fine!   I would like to ask you if the scalability charts are somehow affected if we enable egress queueing in a part of the sessions. To be more specific, we are interested in LC (MOD80-SE) based dual-stack PPPoE sessions. Do the max values of 64K per LC/128K per chassis get affected/reduced if we enable egress queueing in a part of them and if yes, how can we calculate the max supported values for this case?   Best Regards, Dimitris ...

Hi Cristian, Although your question is quite old and you may have found a solution, I will describe what we are doing, although it is not 100% dynamic.   LAC config vpdn-template VPDN-SETTINGS  dsl-line-info-forwarding   RADIUS config cisco-avpair="vpdn:vpdn-template=VPDN-SETTINGS", So, you can push all the dynamic info from radius, including the above cisco-avpair and have only a static command in the LAC, regarding the dsl-line-info-forwarding feature.   Hope it helps :) Dimitris ...

Hi Xander,   Hope you are doing good! Since 6.2.x is still not recommended for BNG so we cannot configure a global session limit (CSCuq24454), I was looking at some workarounds and a couple of questions regarding the following example came up:   bba-group xander session-limit 100 bba-group you session-limit 200   interface TenGigE0/3/0/1.1  pppoe enable bba-group xander   interface TenGigE0/3/0/2.1  pppoe enable bba-group xander interface TenGigE0/3/0/2.2  pppoe enable bba-group you   interface TenGigE0/3/0/2.3  pppoe enable bba-group xander interface TenGigE0/3/0/2.4  pppoe enable bba-group you   How many sessions are supported in TenGigE0/3/0/1? How many sessions are supported in TenGigE0/3/0/2? How many sessions are supported in TenGigE0/3/0? If 200 sessions are terminated under TenGigE0/3/0/2.2, is it possible to terminate any sessions in TenGigE0/3/0/1.1? Thank you in advance, Dimitris ... View more

Hi Ahmed, You are talking about vpdn sessions in LNS, so MAC address cannot be seen over there. Assuming you know the PPP username, you could find the MAC address in the PTA , following these steps (IOS-XE example): PTA#show vpdn session all username xxxxxxx Session id 58757 is up, logical session id 23687035, tunnel id 64195   Remote session id is 57149, remote tunnel id 52482   Locally initiated session   Unique ID is 24721   L2-L2 SSS switching enabled   Session username is xxxxxxx     Interface Te0/2/0.12345678:1234.5678 <output omitted> bbras-llu-kln-22#sho pppoe session | b 24721   24721  21919  abcd.0000.1234  Te0/2/0.12345678      1000  N/A        FWDED                 8843.1234.5678  VLAN:1234/5678 <output omitted> BR ...

Hi Xander, I just noticed that you had answered (I somehow missed the e-mail notification). Although I am not so happy with the answer, I understand the difficulties you are facing and the priorities you have to follow. It seems that we will have to pray for a big player to appear asking for the same feature in order to justify a business case :) Until then, I will keep bothering you, just in case... ;) Thanx, Dimitris P.S. I have noticed that the direct links for each comment (e.g. https://supportforums.cisco.com/document/94171/asr9000xr-bng-deployment-guide#comment-12005526) don't work in this specific thread (they work fine in other threads). Is it something known? Do I have to mention it to someone in order to take a look? ... View more

Thanks for the info and for the global session limit Xander! I will ping you again in a couple of months about the pu ACL :) cheers! ... View more

Hi Xander, Hope you are doing great! I would like to ask if there are any news regarding the per user ACL support, because I haven't seen anything in the release notes yet :( Thanks and regards, Dimitris ... View more

For PPPoE, setting sessions max limit 1 under pppoe bba-group   should do the job. Regards, Dimitris ... View more
