Hi all,

Who is sending the following setting to their ADSL CPEs from RADIUS and why?

Framed-Compression = Van-Jacobson-TCP-IP

Is that attribute even used? We have it active on ADSL circuits
terminated on Cisco 7200 series LNS routers (it's in RADIUS by
default). I am wanting to move users over to ASRs but they don't
support this setting because on the newer ASR1Ks it forces a full
Virtual Access interface rather than a sub-int per subscriber.

I am going to lab turning it off but I'm wondering if anyone out there
is still using it, do you notice any major difference if you are still
using it? When you turned it off was there any noticeable change to

I have found the following threads:


It seems to be a common problem for people migrating to ASRs and
turning it off is required for me to begin migrating users onto ASRs
but I just wondered if there are any potential negatives here or if
its a redundant configuration option.
