Key Challenge

Multi-provider MPLS VPN interconnection
••

•

•

MultiMulti-homed CE– Simplest configuration, no MPLS interaction– Additional access costs, single point of failures, noscalability
VRF to VRF PE interconnect– One PE to PE connection per customer VPN, finetuning of interconnect parameters per customer
VPN (e.g. custom QoS parameters)– Provides visibility of interconnection and individualcustomer VPN– How to increase scalability without impacting
operational visibility
EBGP from AS to neighboring AS– One PE to PE connection between ServiceProviders. High scalability– Limited operational visibility on single end-user
VPN at the interconnection point
MultiMulti-hop EBGP between source and destination ASes
– Same as above, increased scalability because of
the centralized routing information management

Key to MPLS Success

Service Simplicity Advantage when Partnering• Solution is commercially transparent to Partner MPLS
Service– Service simplicity enhances the execution of the sales channel• Provides for an unbundled MPLS service – CEs on Sprint
network can be part of Partner Managed Service• Partner operational & service changes requires little or nointervention from Sprint operations

Key to MPLS SuccessKey to MPLS success is to provide the sameubiquitous reach as IP• Reach is not purely network geography but how you getto the end user through:NetworkTechnology
Universal Access Technologies
Applications… and Partners
Selecting the right partner will be key to your success with MPLS
