About This Network Configuration Example

 

This network configuration example provides an overview of packet optical networking and describes how to implement packet optical networking on PTX Series devices using optical transport network (OTN) parameters and wavelength-division multiplexing (WDM). It offers configurations for 100 Gbps Ethernet interfaces, forward error correction (FEC), MPLS label-switched paths (LSPs), and OTN/WDM parameters to illustrate a sample use case showing how these technologies support preemptive MPLS fast reroute (FRR) with minimal traffic disruption due to link degradation in a converged supercore backbone router network.
