Question

Refer to the exhibit. A network architect is preparing a network design based on the EIGRR. Routers are connected using a cat6a cable type and the inter-router connection speed is limited to 10 Mbps due to distance. During the pilot phase, a DUAL-3-SIA error message is visible. Which action must the engineer take to create a stable design?

Exhibit

Explanation

The DUAL-3-SIA error in EIGRP typically indicates a stuck-in-active state, which occurs when a router is unable to find a route to the destination within the expected timeframe. This can be caused by various factors, such as network instability, misconfigurations, or inefficient routing Considering that the DUAL-3-SIA error usually happens because of route instability or excessive route updates, creating a summary route on R2 can help simplify the routing table and stabilize
