A stub router is one that is connected to no more than two neighbors and should never be a transit router.The Enhanced Interior Gateway Routing Protocol (EIGRP) Stub Routing provides
- improves network stability,
- reduces resource utilization,
- and simplifies stub router configuration.
- The stub router has one exit path from the routing domain and forwards all traffic to a central or distribution router.

- receive-only— This causes the router to not send any routes.
- connected— The router advertises all connected routes to the single neighbor. No redistribution is necessary.
- static— The router advertises all static routes to a single neighbor. The static routes still need to be redistributed into EIGRP to be advertised.
- summary— The router advertises summary routes.
