For example, an NMS is configured to: generate data representative of a common UI comprising UI elements representing a plurality of network devices to be configured in an EVPN topology; receive, via the common UI, an indication of a user input selecting one or more of the UI elements representing selected network devices; generate UI elements representing a plurality of ports of the selected network devices; receive, via the common UI, an indication of a user input selecting the UI elements representing one or more selected ports; and generate, based on the one or more selected network devices and one or more selected ports, topology relationship information of the one or more selected devices to establish the EVPN topology. ## Claims ### Claim 1 A network management system comprising: one or more processors;
