Abstract Abstract
This document specifies a Preferred Path Routing (PPR) mechanism to This document specifies a Preferred Path Routing (PPR), a routing
simplify the path description of data plane traffic in Segment protocol mechanism to simplify the path description of data plane
Routing (SR) deployments with OSPFv2 and OSPFv3 protocols. PPR aims traffic in Segment Routing (SR) deployments with OSPFv2 and OSPFv3
to mitigate the MTU and data plane processing issues that may result protocols. PPR aims to mitigate the MTU and data plane processing
from SR packet overheads; and also supports traffic measurement, issues that may result from SR packet overheads; and also supports
accounting statistics and further attribute extensions along the traffic measurement, accounting statistics and further attribute
paths. Preferred Path Routing is achieved through the addition of extensions along the paths. Preferred Path Routing is achieved
