Configuration Guidelines
******************************************************************
Scenario - An ISP wants to implement Traffic Forwarding for his MPLS L3 VPN
Customers across his Core across different Traffic ENgineering Tunnels based
upon the variuos QoS Levels Offered under Uniform Pipe Mode wherein Service
Provider'S QoS policies conforms to CUstomer's QoS Policies. This way the SP can
Offer Guranteed BW Services accroding to Customer requiremnets for different
classes of traffic such as Voice Payload,Voice Signalling and Normal Data.
Also Service Provider wants to provide guranteed SLA on Traffic Availability
to Customers using Traffic Rerouting across his Core.
Design Considerations and Soultions:
The ISP Can achive this differentiated traffic treatment for different traffic classes by using Class Based Tunnel Selection feature for MPLS Traffic ENgineering Tunnels wherein we make the TE Tunnels EXP aware and then different traffic class of traffic can be dynamically routed across these TE Tunnels.
To achieve the Dynamic Routing of Different Traffic Class across Different EXP aware TE Tunnels Service Provider need to provision PE-PE EXP Aware TE TUnnels on a Per PE Basis and then create a Master PE-PE TE Tunnel which will be EXP-Bundle Master and attach the Individual EXP aware TE
Tunnels as Member to the Master Tunnel.
The Master Tunnel does not needs any priority and BW Specifications but need to be announced to IGP via autoroute.
What happens here is that by building Master PE-PE TE Tunnel and annoucning that into IGP we are making the MP-iBGP Next Hop for the VPNs reachbale across the Master TE Tunnel. Once traffic is forced to Master TE Tunnel , a second level EXP Based routing happens inside one of the EXP Aware TE Tunnel Matching the EXP of the Packet. If the EXP matches no EXP aware TE Tunnel the packet is sent across an EXP aware TE Tunnel configured with default EXP. If none of the tunnels are confifured with EXP Default the packet is sent acorss the EXP aware TE Tunnel
configured for Lowest EXP Value.
The MPLS TE Router ID needs to be same as of MPLS Router ID and should be the one used for the MP-iBGP Loopback Peering IPs
The SP also needs to match the incoming IP PREC/DSCP form Customer Edge and translate them to the EXP values as configured across the different EXP aware TE Tunnel to achive desired traffic forwarding. This is same as part of Short Pipe Mode MPLS VPN QoS Operation.
For achieving Traffic Rerouting across their Core , Provider needs to setup backup tunnels across Core and use MPLS TE Fast Reroute Feature on the Primary Tunnels and protecting the Core links with
backup tunnels.
Caveats: This design will suffer from the n*(n-1)/2 EXP Aware PE-PE TE Tunnels for achieving full mesh reachability across its core.

Problem Condition 1- ISP's Core Link from PE1 to P1 goes Down breaking the Primary
Silver LSP and the TE Tunnel
Traffic gets rerouted across ISP's Core Link from PE1 to P2
as
Forward Traffic Path
Silver (DSCP/COS af31,cs4 and default/4 3 0 ) CE1A-PE1-P2-PE2-CE2A
Reverse Traffic Path
Silver (DSCP/COS af31,cs4 and default/4 3 0 ) CE2A-PE2-P2-PE1-CE1A
Problem Condition 2- ISP's Core Link from PE1 to P2 goes Down breaking the Primary
Gold LSP and the TE Tunnel
Traffic gets rerouted across ISP's Core Link from PE1 to P2 as
Forward Traffic Path
Gold (DSCP/COS ef/5 ) CE1A-PE1-P1-PE2-CE2A
Reverse Traffic Path
Gold (DSCP/COS ef/5 ) CE2A-PE2-P1-PE1-CE1A
Problem Condition 3- ISP's Core Link from P1 to PE2 goes Down breaking the Primary
Silver LSP and the TE Tunnel
Traffic gets rerouted across ISP's Core Link from PE1 to P2
as
Forward Traffic Path
Silver (DSCP/COS af31,cs4 and default/4 3 0 ) CE1A-PE1-P2-PE2-CE2A
Reverse Traffic Path
Silver (DSCP/COS af31,cs4 and default/4 3 0 ) CE2A-PE2-P2-PE1-CE1A
Problem Condition 4- ISP's Core Link from P2 to PE2 goes Down breaking the Primary
Gold LSP and the TE Tunnel
Traffic gets rerouted across ISP's Core Link from PE1 to P2 as
Forward Traffic Path
Gold (DSCP/COS ef/5 ) CE1A-PE1-P1-PE2-CE2A
Reverse Traffic Path
Gold (DSCP/COS ef/5 ) CE2A-PE2-P1-PE1-CE1A
The Same traffic rerouting happens for ISP's Core Link on PE2 Going down.
