3. Static Routing - metrafonic/Cisco-Cheatsheet GitHub Wiki
Configure a static route
It is important to remember that in a scenario where you may not need to add a static route on your gateway router to access a different router, you will most likely need to configure a route back to the client. The remote router will need a route to your internal subdomain via your access router.
Recursive
(config)# ip route [nettID] [subnet] [router ip to use]
