Cisco: Follow the network path / route and what devices it’s traveling though to find a particular host on the LAN.

Follow and find the network path / route and what devices it’s traveling though to reach a particular host on the LAN.
The network I work on has a number of Cisco routers and Cisco switches along with Ciscco ASA with many servers and workstations on it, along with many subnets using vlsm. The routing table is out of date and I want to track down the routing paths to find out if the routes are still needed or if there is a better path that can be used along with documenting the network. I need to rely on the routing table, since there is no documentation to follow such as network diagrams, ip address logs ect..
I’d like to find a good lab with gns3 or at least some good documentation explaining how to track down routing paths. I’m going to first track down the static routes, and then OSPF and BGP routes.
I understand the technology, but just need some good examples to go by for doing this.
