[c-nsp] VPDN multihop/forwarding not working

[CiscoNSP_list CiscoNSP_list]

Hi Guys,  Have a 7200 (LNS) that terminates DSL tails from multiple carriers (Using our radius for auth) - Attempting to forward connection requests for a specific realm to an alternate LNS (So create an L2TP tunnel)  Have the following vpdn setup, but the tunnel is not getting created to the "initiate-to" IP....and if the new realm DSL accounts are created on our radius server, they auth?  vpdn enable
vpdn multihop
vpdn aaa attribute nas-port vpdn-nas
vpdn logging
vpdn history failure table-size 50
vpdn search-order domain  
vpdn domain-delimiter @ suffix
vpdn domain-delimiter / prefix   vpdn-group TEST
