Constraints in dynamic segment routing traffic engineering

“

- [Instructor] Dynamic Segment Routing traffic engineering, or SRT, allows networks to dynamically calculate and optimize traffic paths based on specific requirements or constraints. Constraints are rules that determine whether a particular path can be used. These constraints include metrics like IGP cost, delay, bandwidth, or path affinities. What is affinity in segment routing? Affinity is a mechanism to take links with certain attributes like color-coded names like green or blue that defines their characteristics. These affinities can then be used as constraints in SRT policies to include or exclude specific links during path computation. In segment routing, you can define an affinity with a unique name and associated it with a bit position. The bit position identifies the affinity in a bit mask format. Bit position 0, 0x, quad zero, 0001. Bit position 1, 0x, quad zero, 0002. Bit position 2, 0x, quad zero, 0004. Commands to configure affinity. Enter segment-routing traffic…
