[c-nsp] Can Cisco be used for LAC features?

[James Bensley]

Hi All,

We take wholesale ADSL from multiple provides but also are an LLU
provider with on-net ADSL.

I'm trying to configure up an LAC in our lab but not getting anywhere...

I have seen an old post here where a guy wants to set up an LAC but
its pretty strait forward, just forwarding tunnels on to an LNS:
http://www.gossamer-threads.com/lists/cisco/bba/82134

I am trying in the lab to create a LAC config that will query our
RADIUS for PPP authentication because the RADIUS will return different
tunnel end points based on the user authenticating in.

With the RADIUS responses to our wholesale providers
user at customer1.net will prefer LNS1 and user at customer2.net will prefer
LNS2. I wish to re-create this internally. All config examples and
guides I can find on the internet are for creating static VPDN groups
that initiate a tunnel to 1.2.3.4 for uses that mactch domain
customer1.net. I would have to create a VPDN group for every domain.

Does Cisco IOS not support more typical wholesale LAC features
operting on the output of RADIUS and also supporting the concept of
query RADIUS IP 1.1.1.1 for all @domain1.net user and query RADIUS
2.2.2.2 for all @domain2.net user queries?

I am labbing this with 7200 series routers running
c7200-advipservicesk9-mz.152-4.M7.bin. We also have ASRs but I was
hoping to stick to these very well known platforms first then try the
ASRs.

Cheers,
James.
