Sort of. The part up to tunnel lookup is correct. TOS stamping takes place on the CE along with some sort of rate limiting usually. Mapping the packets to tunnels would be done on a routing basis I believe. If I’m not mistaken you can also use half-duplex VRF to do this as well. As the CE TOS bit is encapsulated in the MPLS info the experimental bit will be used. Make sense?

Does it imply that the CEs linked to the ingress PE would send IP packet’s TOS field to mark a QoS service.

And additionally the PE would lookup the TOS field on all its inbound CE interfaces and mark EXP bit and forward them to any of the TE tunnels that which may have an EXP bit mapping?

 

Thanks

Absolutely. You can use half-duplex VRF routing as well as MPLS experimental bits to define how you would like traffic from a customer to be handled. A search on Cisco’s site will show you the necessary steps.

Can QoS be applied to Layer 3 MPLS VPNs in such a manner that, two customers connected to the same ingress PE router but offered two types of services like GoldVoIP and SilverVoIP and two TE tunnels having different Path options but terminating together on a common egress PE?

 

Since the Egress PE for the both VPNs is the same, is it possible to have VPN traffic classified and routed to different tunnels?

 

Could someone pass a link to any cisco or juniper configuration guide ?

 

Thanks
