[mpls-linux-general] Help : trying to Run MPLS and FreeS/WAN on the same box

[Murthy S. A. <msa...@cs...>]

I am trying to run MPLS on top of IPSec (encapsulate IPSec/IP packets
within MPLS).

what I am trying to setup is

privatesubent1<-->VPNGateway<-->MPLSLER<-->MPLSNetwork<-->MPLSLER<-->
VPNGateway<-->privatesubnet2

and , I am trying to install the VPNGateway and MPLSLER on the same box
(one box for each of these pairs).

I am able to setup JUST a VPN tunnel with Freeswan. I have downloaded and 
comipled mpls-linux, MPLS enabled MPLS and iproute2. I am just lost at
how to have MPLS read from , and write to, the IPSec module. (and make 
freeswan read from and write to the MPLS module). I imagine it
is done with iptables and iproute2, but does anybody have any examples ?

any help will be greately appreciated. My network nodes are all RH8 boxes.
I have searched the net with all combinations of MPLS and IpSec I could 
think of,and did not have any luck. So, if there is indeed 
something outthere, please point me to that. 

Thanks
