A system can check links of a plurality of networks that use different routing protocols. The system derives link states from a copy of a routing database according to the format of the routing database. The derived link states are formatted into a reference format and compared to reference link states to determine link state differences. A reference link state file can be updated based on the determined link state differences. A method involves obtaining a copy of a routing database from a router and deriving current link states from the copy of the routing database according to the format of the routing database. The derived link states are formatted into a reference format. The current link states are compared to reference link states to determine link state differences. User-friendly router names and router interface names are obtained from, for example, a router configuration file. IP addresses in the link state differences are mapped to the router names and router interface names. The link state differences can then be presented in a user friendly presentation to the user including router names and router interface names.
