[c-nsp] Dialup with MPLS

Generally, CE is unaware (and should be) of all things MPLS. 

What I think is happening in your case is that the Telco network is not yours, you are aggregating a few PPP tails at your CE (which is your demarcation) and you want them to belong to different VRF's. 

If thats the case, check with your SP and you could prolly do CSC (carrier servicing carrier) MPLS VPN model. Thereby your CE can talk label switching with PE. 

Check out this url (and search csc vpn on cco)

Hi Nick,
 
Thanks for the reply. But my scenario is a typical Telecom network where user is using mobile to access the data service. I don't have router ports to create MPLS VPN. This network is a MPLS enable network for TE. All the users are using their phone to connect to network using EV-DO / 1X-RTT network. Can I create end to end TE tunnel? my topology looks like - 
 
                                           Router 1
 
         
                     Router 2                               Router 3
 
                                                                          Router 4
 
                                                               router 5                router 6
 
here router 1 2 and 3 are in mesh and AAA is attached to router 3. router 4 is attached to router 3 and router 5 and 6 are attached to router 4.  A user dial from CDMA network that is attached to router 5 and get authenticated by AAA attached to router 3. Now router 1,2 and 3 are part of MPLS core, router 4 is PE router and router 5 and 6 are behaving as CE router. Once the mobile user get the IP, he/she lands on router 5 which is currently CE router (this is just the logical view, all above shown routers are part of same network). In this scenario, can I implement end to end MPLS with TE? 
 
Pls write me back if you need more clarification.
 
Thanks
Vikas

	If so, 2 ways to do it
	
	- your NAS is configured as the PE, where upon DIALUP & authentication, 
	RADIUS sends VRF attributes and puts the user in appropriate VRF
	- or deploy VPDN, and L2TP multihop from the NAS to LNS (which is a PE)
	and have radius send VRF attributes to put into a VRF.

	Hi,
	
	In a scenario where user can access Internet or other data services 
	using
	wireless medium (CDMA phone to access data on laptop / PC), is it
	possible
	to implement MPLS on dialup?
	User gets an IP through PDSN (PPP) and now it is connected to the
	network.
	In core and distribution layer MPLS can be implemented using Core as a 
	MPLS
	core and distribution layer as a MPLS Edge LSR. Can we implement end to
	end
	MPLS? Like as soon as user get an IP and come on the first router on the
	network, it should be switched using MPLS. In the normal scenario, we 
	need
	to configure last router that is connecting to distribution layer router
	(edge lsr) as a CE router.
	
	
	Thanks
	Vikas
