[c-nsp] Cisco DSL Config Question - Multiple Domains

[Frank Bulk]

Didn't we talk about this just 3 weeks ago?

Or is this a continuation of that discussion?

Subject: [c-nsp] Cisco DSL Config Question - Multiple Domains

I'm hoping someone can help me here..;)  We have a Cisco 7206VXR that we
use for DSL termination from a telco via l2tp tunnels.  Below is some
snippets of the config.  Today, everything works fine but our goal is to
split up three domains coming in **without** using proxy-radius and/or
changing radius at all (don't go there). ;)

Our telco provider who is sending us the l2tp tunnels runs Juniper and
can route each domain to a separate loopback on our side.  This all made
sense until I started looking at vpdn-group configuration etc...

If they terminate each domain onto a separate loopback interface, how
can I bind that to a separate virtual-template where I can also define
separate radius servers and Ip pools for each domain?  Is there a way to
do this?  I had this figured out I thought until I found the
"virtual-template 1" statement on the vpdn-group.. Is there a way to
remove this and do it from the loopback instead?

Config:

aaa group server radius ABC
 server-private xxx.xxx.xxx.28 auth-port 1812 acct-port 1813 key 7
