The scenario
A wholesale IP/MPLS backbone connects multiple edge routers through a partially meshed core, using BGP-LU for label distribution and traffic engineering for optimal path selection.
What is in this drawing
Read the decisions behind it.
01
Mesh layout for core resilience and any-to-any LSPs
02
Dual-homed PE routers to two core nodes for redundancy
03
Route reflectors reduce full-mesh BGP sessions
When designing or documenting a service provider MPLS backbone with separation of core (P) and edge (PE) roles.
