A stub router sends a special peer information packet to all neighboring routers to report its status as a stub router.
Any neighbor that receives a packet informing it of the stub status does not query the stub router for any routes.
Router(config-router)# eigrp stub [receive-only|connected|static|summary]
-
-
connected: Permits stub to send connected routes (may still need to redistribute).
-
static: Permits stub to send static routes (must still redistribute).
-
summary: Permits stub to send summary routes.
