Hi All,
I wanted to create PE to PE traffic engineered tunnels with guaranteed bandwidth using mpls experimental bits. On ingress PE i am mapping all traffic in to four classes Platinum (EXP 5) , Gold (EXP 4), Silver (EXP 3), Bronze (EXP 2). All core interfaces are 10Gbps and egress scheduling configured for platinum- 2.5Gbps, gold- 2.5Gbps, silver- 2.5Gbps, bronze- 2.5Gbps.
Ingress to egress dynamic tunnel has to establish with guranteed bandwidth for platinum traffic 2.5Gbps. For four types of traffic I required 4 LSPs from ingress to egress.
Can this requirement be done by diffser-te in cisco? If possible, please suggest helpful docs for configuration.
Regards

Hi
The requirement is full filled by DS-TE. As per RFC 3564, describes following 3 application scenarios indicating the need for DS-TE:
1. Limiting proportion of Classes on a link
2. Maintain relative proportions of traffic on links
3. Guaranteed bandwidth services
TE Class Definition in Cisco IOS
mpls traffic-eng tunnels
mpls traffic-eng ds-te mode ietf
mpls traffic-eng ds-te te-classes
te-class 0 class-type 1 priority 0
te-class 1 class-type 1 priority 1
te-class 2 class-type 0 priority 2
te-class 7 class-type 0 priority 7
User-defined Constraints for DS-TE
interface Tunnel 30
ip unnumbered Loopback 0
tunnel mode mpls traffic-eng
tunnel mpls traffic-eng priority 7 7
tunnel mpls traffic-eng path-option 2 dynamic
tunnel mpls traffic-eng bandwidth 1000 class-type 1
tunnel destination 5.5.5.5
