Before the maintenance window, know exactly where the traffic will go: Topolograph rebuilds your network the way its routing protocols see it and lets you break it safely on screen. Upload one router's LSDB output, from Cisco, Juniper, Arista, FRRouting, MikroTik, and a dozen other vendors, and the whole area's topology appears as an interactive graph, because the protocol already flooded it everywhere. Compute the shortest path between any two routers and see every equal-cost alternative with per-link loads, then fail a link or a node and watch SPF recalculate: which pairs moved to backup, which are left with none, and how the load shifted on every surviving link. Search the graph for prefixes, MAC addresses, or any network element, plan an MPLS TE path against real bandwidth attributes, and compare snapshots from different moments to answer what changed before the incident. Collectors can stream live OSPF, IS-IS, and BGP events over GRE, BGP-LS, or BMP so the timeline replays the network at the moment things broke, and a REST API, Python SDK, and MCP server let your own tooling and AI agents ask the same questions.
