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

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
