Explanation
When EIGRP is deployed on access layer switches, they should be configured as EIGRP stub routers. Access layer switches are leaf nodes - they have connected end-user networks but should never be used as transit paths between distribution switches. Configuring stub routing tells EIGRP neighbors that the access switch only advertises its directly connected or summary routes and will not be queried for routes to other networks. This dramatically reduces EIGRP query propagation, speeds up convergence, and prevents access switches from inadvertently becoming transit routers.
