Configuration Guidelines
******************************************************************
Scenario - An ISP having a big geographic presence 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 Short
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.
ISP has a ISIS Level-2 Core Backbone with Edges in ISIS Level-1 Domain
Design Considerations and Soultions:
ISP Wants to offer Classes of Traffic as Premium (Low Latency), Classic (Gold,Silver)
The ISP Can achive this differentiated traffic treatment for different traffic classes by using Diff Serv-TE and 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.
"Thing to be considered here is that ISP has a huge geographic presence and Creating PE-PE Full meshed TE tunnels is a huge overload
for the network resources and hence we create full mesh of P-P TE Tunnels. Also we create regional boundries for the POP Locatiosna
and using PE Route-Reflector for each region and making full mesh of Route Reflcectors for BGP VPNv4 Neighbourship.
To achieve the Dynamic Routing of Customer Traffic across Classic Traffic Class across Differet EXP aware TE Tunnels Service Provider
need to provision P-P EXP Aware TE TUnnels on a Per Region Basis and then create a Master PE-P 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 Dynamically routing Customer Traffic Across Premium -Low Latency Tunnel SP needs to Provision TE Tunnels with DS-TE Subpool
Then Provider Needs to force the MPLS L3 VPN Traffic down the tunnel on the basis of communitiy tag idenitifiers which have been set
as standard based on regional separations.
Challenge: This design has a greater challenge in dynamically routing MPLS L3 VPN Traffic over the Premium Tunnel as this Tunnel is
not member of Master Tunnel and not EXP Aware (can be exp aware itself but can not be made part of the already existing EXP Aware
Tunnels). The Problem is that we are building P-P Tunnels and Forwarding MPLS L3 VPN Traffic over MP-iBGP Sessions PE-PE and if we
have just 1 PE-PE MP-iBGP Peering,we can send traffic over only either the EXP Aware or DS-TE Tunnel,or we can load balance that but
we can not dynamically choose either of this tunnel by having just a single MP-iBGP Sessions between same PEs.There is one solution
to this issue we can use 2 MP-iBGP PE-PE Peerings per PE over 2 different loopbacks on each PE. Then we can have one Loopback
reachable via the EXP Aware TE Tunnel by setting the IGP Metric and have other Loopback reachbale via DS-TE Tunnel using a Static
Route across the DS-TE Tunnel on the P Router for 2nd Loopback and then redistributing it towards PE ROuters with better metric.
Now in effect we have 2 MP-iBGP Sessions or 2 vpnv4 traffic paths between same PEs.All we need to do is to use BGP Communities over
vpnv4 peering to set the next hop to desired MP-iBGP Peering.
Caveats: Having 2 MP-iBGP Peering between same PE-PE will be an overhead for ROuter Resources but quite a good dynamic traffic
engineering option
Scenario Detail: ISP has a big geographic presence and he has divided his SP Domain into 16 regions
NE,NW,NS,NN,SE,SW,SN,SS,EE,EW,EN,ES,WE,WW,WN,WS for reducing the number of MP-iBGP Full Mesh Sessions
Further States have been mapped onto these regions and cities have been mapped onto POPs into these States so that we have something
like this in our network
nwst1cit1pop1--Means PoP#1 under North-West Region in the Citi #1 under State#1.
Then we setup one RR per POP (2 for Redundancy) and different POPs under same Region Have MP-iBGP Full Mesh.We have Region Boundry
RRs which again have Full Mesh with each other.
This way we bring up the TE Hieracrhy up in Level as well as the MP-iBGP Peering for MPLS L3 VPN Traffic
We use well defined communities per region basis per PE Router and Per RR. EU who wants to have Low Latency QoS needs to send the
Routes requiring Premium Services marked with well defined TAGs per PE based upon which PE will set a standard community recognises
by RR and matching which RR will set the NH to the 2nd Loopbac being know via the DS-TE Tunnel.
The Normal Classic Traffic Class need to be sent marked by any TAG and will be dynamically routed across EXP Aware TE Tunnels based
upon the IP PREC/DSCP values.
For Scalabiltity between Inter-Region RR Communication, RR will have standard community value which will be sent to its RR Peers and
when matched upon will set the NH over DS-TE learnt Loopback for the MP-iBGP Peering between Inter-Region RRs.
This way the Community values of PE Routers will be local to the region and RRs will be Local between Inter-regions
