Abstract
Many networks configure the IGP link metric relative to the linkcapacity, and high bandwidth traffic gets routed per the linkcapacity. Flexible Algorithms provide mechanisms to createconstraint-based paths in an IGP. This specification documents ageneric metric-type and a set of bandwidth-related constraints to beused in Flexible Algorithms.
This document updates RFC 9350.
