Segment Routing (SR) and Topology Independent Loop Free Alternates (TI-LFA)

Segment Routing (SR) and Topology Independent Loop Free Alternates (TI-LFA)

In previous blogs, we explained how a network operator can use Segment Routing (SR) to implement traffic engineering policy. In this blog, we will introduce Topology Independent - Loop Free Alternates (TI-LFA). TI-LFA is a fast-reroute (FRR) mechanism that leverages SR.

 

To understand TI-LFA, we must first understand its predecessors, Loop Free Alternates (LFA) and Remote Loop Free Alternates (RLFA).

Segment Routing (SR) And Traffic Engineering (TE): Part Two

In last week’s blog, we followed a typical service provider through the early stages of SR deployment. While this blog did not reflect the actual deployment experiences of a real service provider, it did reflect issues that a real service provider faces as it plans for SR deployment. In this week’s blog, we will continue to address those issues as we continue to follow our typical service provider through the stages of SR deployment.

 

Initially, the service provider operated the IPv4 network depicted below.
