[c-nsp] Design Recommendation for Dual WAN Connectivity with Multiple MPLS Service Providers

[Muhammad Atif Jauhar]

Greetings,

We are planning to deploy two WAN links from different Service Providers,
both offering MPLS connectivity with BGP peering. As part of the design
review, we would like to align on the best-practice approach to ensure a
stable, loop-free, and predictable routing architecture.
Given the use of multiple MPLS providers with potentially different latency
characteristics, our key objectives are to avoid routing loops, prevent
asymmetric traffic issues, and ensure controlled traffic engineering and
failover behavior.
Any recommendations or considerations based on your experience,
particularly with respect to MPLS interconnects and BGP traffic engineering.

Regards,

Atif.
