EIGRP network summarization on edge routers creates explicit boundaries for DUAL (Diffusing Update Algorithm) queries. When a route behind a summary becomes unreachable, queries for that specific route are contained within the summarized area, as the router performing the summarization responds authoritatively. This significantly reduces the propagation of queries across the network, leading to faster convergence and less CPU overhead on other routers.

Route filtering controls which routes are advertised or accepted, but it does not directly prevent EIGRP queries from being sent out or define query boundaries.

EIGRP uses 'stub routers' to contain queries within a network segment, but the question specifies 'stub areas' (an OSPF concept) and suggests configuring 'non-edge routers,' which is generally not the best application for EIGRP stub functionality.

Using different EIGRP processes creates separate routing domains that require redistribution, adding complexity and not directly addressing the reduction of query range within a single logical EIGRP domain.
