The system provides you with two methods to rebuild topology to keep all topology links up-to-date when you network change.
IPv4 L3 Topology is built automatically after Live Network Discovery and scheduled discovery tasks. You can also customize whether to build IPv4 L3/IPv6 L3/L2 topology and L3 VPN tunnel automatically during a scheduled benchmark task. See Benchmark Task Settings for more details.
The accuracy of L2 topology relies on IPv4 L3 topology, so it is recommended to build them together during a benchmark task. The rebuilt-topology is calculated based on existing data in the Current Baseline.
