We are facing a mpls-backbone with vpns. Our customer requires that these vpns get guaranteed bandwidth. We have found a lot of information about VPN-QoS over MPLS but no configuration examples. Could you please tell us how to configure such a requirement?

Check out this webpage ..Its a great place to start: http://www.cisco.com/warp/public/cc/so/neso/vpn/vpnsp/mpls_wi.htm
Here is a configuration I found as well: http://www.cisco.com/warp/partner/synchronicd/cc/pd/si/ig8400/prodlit/igxm_rg.htm
You might want to get some help the first time you do it, because its rather tedious the first time through.

I am in the same boat here. I am looking to to push traffic across TE-tunnels with explicit paths from particular VPNs using RSVP signalling to build bandwidth guarantees, but it seems that since the tunnels are using the BGP next hop to determine which path to use when forwarding traffic, I can't make traffic take any explicit path since the actual destination of the tunnel is not in the main RIB.
This seems to work fine when the destination appears in the main routing table, but the minute you push the network into a VRF the router only has the MpBGP next-hop address to use (since you can't make the tunnel examine the VRF RIB), which is reachable through 3 different directions in my topology...
Are there any configuration examples available showing how to build path selection using VPNs and TE-tunnels together? This is an IP-only environment.

We offer a number of resources at http://www.cisco.com/tac including configuration examples and white papers. If you are unable to find what you are looking for specifically, please open a case with our technical assistance center for help with this issue. You may open a TAC cas online at http://www.cisco.com/tac/caseopen
If any forum members have some recommendations, please post them to this thread.
Thank you for your inquiry.

As well-know,MPLS have 3 applications,VPN,TE,COS.
Several different methods exist for supporting CoS across an MPLS backbone, the choice depending on whether the core has label switch routers (LSRs) or ATMLSRs. However, the CoS building blocks are the same: CAR, WRED, and WFQ.
Cisco has detail configuration manual.If you can't find it.I would like to mail it to you.

i do not have details regarding the configuration of the CoS parameters such as CAR,WFQ etc.
Cud u please arrange to provide these details?

Hi kunpeng,
Would you please send me the detailed configuration manual by mail?
Thank very much!

There are 2 doc. on CCO:
MPLS CoS over ATM: Multi-VC TBR (using CAR)
http://www.cisco.com/warp/customer/121/mpls_cos_atm.html
MPLS CoS over ATM: CoS Map
http://www.cisco.com/warp/customer/121/mpls_cosmap.html
Alternatively You can use our product ( Orchestream) witch will config Cisco router to do MPLS, MPLS/VPN and QoS.
