[l2tpns-devel] cisco vrf style vpns with l2tpns

[Ingo F. <if...@xi...>]

Hello,

I would need a feature like cisco vrf, where via a radius attribute the 
ppp session in a l2tp tunnel (not the whole tunnel) could be terminated in 
a virtual router, with its own ip-stack.

Currently I have 2 ideas how todo this with l2tpns:
*) with linux vrf:
 	http://sourceforge.net/projects/linux-vrf/
 	pro: 100% like cisco
 	con: little bit old, no new works at the project
*) with an own cluster slave, good firewalled that only l2tp packets pass
 	toward the master; I assume that all l2tp traffic is relayed via
 	the master?
 	pro: easy?
 	con: no failover, breaking master-slave, ...
*) with own walled garden plugins
 	pro: ?
 	con: ?
*) build a l2tp tunnel switch (as cisco and juniper have) in front and
 	split into real hardware
 	pro: simple setup
 	con: much hardware, single point of failure, LNS/LAC to implement

What solution do you think is the best one I should try to implement?

Kind regards,
 	ingo flaschberger
