[cisco-bba] multihop vpdn & adsl

[Tassos Chatzithomaoglou]

I'm trying to implement the following:

      ATM          ETH
LAC -----> LNS1 ------> LNS2


LAC is already terminating PPPoX sessions and is forwarding (L2TP) them to LNS1.
I want LNS to forward specific (per username/domain) sessions to LNS2.


Example 1:

user1 at test should be terminated at LNS1
user2 at test should be terminated at LNS2 (after passing from LNS1)

Example 2:

user at test should be terminated at LNS1
user at test1@test should be terminated at LNS2 (after passing from LNS1)

Should i implement "vpdn authen-before-forward" on LNS1 and provide the appropriate vpdn 
config (for termination on LNS2) through my aaa server?
