Abstract

Techniques are described for selecting paths in accordance with service level agreements. For example, spoke and hub routers may advertise routes associated with virtual routing and forwarding (VRF) instances mapped to service level agreements (SLAs). A virtual route reflector of an intermediate router may receive route advertisements and may add respective path communities associated with particular links selected based on link state measurements in accordance with the SLAs. The hub or spoke routers may receive the route advertisements including a respective path community and install the selected path as a next-hop for a given SLA. In this way, spoke and hub routers may forward traffic on links that satisfy particular SLAs such that Quality of Experience (QoE) for an application may be restored or improved.
