Flexlink

In this section:

1. Flexlink Overview
   Flexlink is a link redundancy feature that provides Layer 2 resilience. Flexlink provides link redundancy at a faster network convergence rate than Spanning Tree Protocol (STP) and its variants (RSTP and MSTP). Generally, it is deployed at the access layer where the switch has dual uplinks to the distribution layer. Flexlink re-aligns the forwarding path on the local switch where it is configured and has no role in adjusting the forwarding path on other switches in the network.
