This is definitely possible, and we do this on a large number of platforms.
An example config would be; vpdn enable vpdn multihop vpdn logging vpdn logging local vpdn logging user vpdn logging tunnel-drop no vpdn history failure cause normal vpdn history failure table-size 50 vpdn search-order domain vpdn-group TESTGROUP description Test Group for VPDN Multihop request-dialin protocol l2tp domain xyz.com initiate-to ip x.x.x.x source-ip y.y.y.y local name 7206L2TP l2tp tunnel password 7 xxxxxxxxxxxxxxxxxxxxxx l2tp tunnel timeout no-session never This setup uses static configuration, however you can do the same thing via radius, and allows you to scale to many termination points and dynamically change the destinations. We use both, let me know if you want a sample radius setup. We have dial platforms that use "vpdn search-order dnis", but in this setup, the router checks the @domain of the username and then creates an L2TP tunnel to the "initiate-to" IP. It is possible to terminate PPP sessions and forward them on via L2TP on the same chassis.

Hi Guys, We currently run 7200's as LNS for DSL services (Carrier has multiple LACs and sends session requests for various realms to our LNS's, which we then auth via radius). Is it possible for one of our 7200's to receive vpdn sessions for a given realm, but then establish an L2TP tunnel to one of our other LNS's and have the session terminate there? (So L2TP tunnel from LAC(Carrier)->LNS(7200), then based on realm, the 7200 creates another L2TP tunnel to one of our other 7200's where the session will be auth'd/terminated) Thanks in advance. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
