Routing protocols such as Routing Information Protocol (RIP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP) are fundamental topics in computer networking education but are often difficult for students to master through traditional lecture-based methods. Their dynamic and distributed nature requires practical exposure to enhance understanding. Cisco Packet Tracer, a network simulation platform developed by Cisco Systems, provides an interactive environment for configuring, observing, and troubleshooting routing protocols without the need for costly physical laboratory infrastructure. This study evaluated the effectiveness of Cisco Packet Tracer simulation-based instruction in improving undergraduate students’ understanding of routing protocols. A quasiexperimental pre-test/post-test control group design was adopted involving 186 students enrolled in Computer Networks courses across two institutions. The experimental group (n = 94) participated in six structured Packet Tracer laboratory sessions covering RIP v2, OSPF, and EIGRP, while the control group (n = 92) received conventional instruction supported by textbooks and static diagrams. Student performance was assessed using a validated Routing Protocol Knowledge Assessment (RPKA), while motivation was measured using an adapted Instructional Materials Motivation Survey (IMMS). Results showed that the experimental group achieved significantly higher post-test scores than the control group (74.3 vs. 61.8; p < 0.001), with a large effect size (d = 1.23). The greatest improvement occurred in diagnostic reasoning skills (d = 1.38). Knowledge retention was also significantly higher in the experimental group after six weeks (71.6 vs. 55.2; p < 0.001). Additionally, students exposed to Packet Tracer reported higher motivation, particularly in relevance and confidence. The findings demonstrate that Cisco Packet Tracer is an effective and accessible tool for enhancing learning, retention, and engagement in routing protocol education.
