LAC -> LNS - pushing "dsl-line-info-forwarding" via radius server?

[Christian Steger]

hi community,

i receive on my LAC DSLAM lineparameter like "circuit-id/remote-id" as well as the "actual-bandiwth-up/down".

to push this parameters to an LNS i have to add within the vpdn-group (request-dialin) the prameter "dsl-line-info-forwarding".

my LAC is an cisco ASR1001 running Cisco IOS XE Software, Version 03.16.05.S (gues its the latest available)

this works fine... - i try to avoid this in an static setup. - i wanna push everything via radius...

so my question is:

according to this radiusattributes doing an l2tp dialout to the remote-LNS

what attribute i have to add to push the "dsl-line-info-forwarding" on the LAC from the radius to the LNS?

"username" NAS-Identifier := "LAC-Node", Auth-Type := Accept 
                        Tunnel-Assignment-ID:0 = LNS-Node,        
                        Tunnel-Type:1 = L2TP,               
                        Tunnel-Medium-Type:1 = IP,                  
                        Tunnel-Password:1 = password,     
                        Tunnel-Server-Endpoint:1 = 192.168.0.2,           
                        Tunnel-Assignment-Id:1 += "Tunnel1",

i have tried to use on local configuried vpdn-group "DSL-FORW" and to push it via radius attribute "Tunnel-Private-Group-Id"

vpdn-group DSL-FORW
 dsl-line-info-forwarding

but without success..

any ideas ?

thank you!

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 :)
