[cisco-nas] VPDN Problems

[Nikolas Geyer]

Hi all,

Am a newbie around here looking for any assistance possible. We are
currently purchasing a wholesale ADSL product off our backbone provider,
which terminates on our LNS via L2TP (which is a Cisco 2611XM).

The setup works great, all ADSL customers terminate with us. But is it
possible to act as a "virtual LAC" of sorts, so depending on the domain the
customer is connecting from, our LNS then tunnels the connection via L2TP to
another LNS? Below is an excerpt of the config from the router;

vpdn enable
vpdn multihop
vpdn ip udp ignore checksum
vpdn search-order domain
vpdn domain-delimiter @ suffix
!
vpdn-group ACIS
 request-dialin
  protocol l2tp
  domain acis.com.au
 initiate-to ip 203.14.230.5
!
vpdn-group connect-dsl-direct
! Default L2TP VPDN group
 description Terminate local PPP ADSL sessions here
 accept-dialin
  protocol l2tp
  virtual-template 1
 local name lns.core1.can.infinite.net.au
 lcp renegotiation on-mismatch
 l2tp tunnel password 7 06152B241B19380B03344152
 ip mtu adjust
!

As I said, this works great for our clients, but when someone logs in with
the domain @acis.com.au, we want the LNS to then tunnel it off to another
LNS, but its still trying to authenticate and terminate locally.

Any help would be appreciated.
