What is the EIGRP data structure that lists all networks EIGRP found and their connected interfaces?

• A. Routing Table
• B. Topology Table
• C. Adjacency Table
• D. Neighbor Table

Answer: (B)

In EIGRP, routes learned from neighbors are stored in the Topology Table. This table contains every network EIGRP has discovered and shows how each network can be reached, including the exit interface (the connected interface through which the route is learned). It’s the place where all potential paths are kept and evaluated, with each entry carrying metrics and next-hop information. The Routing Table, by contrast, holds only the best path to each destination that is installed for forwarding. The Adjacency (or Neighbor) Tables track which routers are directly connected and have formed EIGRP neighbor relationships, not the reachability of networks themselves. So the structure that lists all networks EIGRP found and the interfaces used to reach them is the Topology Table, because it records every learned route and the associated exit interface, providing the complete view EIGRP uses to compute the best paths.
