Topology
This document uses a lab setup with four ONS 15454 nodes, namely 15454a−105, 15454b−108, 15454c−107
and 15454d−104 (see Figure 1). These four nodes form a star network, where 15454a−105 serves as the
and 15454d−104 (see Figure 1). These four nodes form a star network, where 15454a−105 serves as the
