Network fabric visualization and management

In one example embodiment, a server, using Border Gateway Protocol Link-State, obtains, from a particular network node of a plurality of network nodes in a network fabric configured for segment routing, network topology information of the plurality of network nodes including segment identifiers of the plurality of network nodes. The particular network node gathered the network topology information from other network nodes of the plurality of network nodes using an underlay routing protocol. Based on the network topology information, the server generates a visualization of a topology of the network fabric including the plurality of network nodes and a plurality of links connecting the plurality of network nodes.
