The document discusses the routing protocol EIGRP (Enhanced Interior Gateway Routing Protocol). It describes EIGRP as a classless distance vector routing protocol that was originally proprietary to Cisco but is now multi-vendor. It directs students to view a video on fundamental EIGRP configuration and verification that covers topics like classful vs classless routing, auto-summarization, autonomous system numbers, wildcard masks, and passive interfaces. Students are then asked reflection questions to test their understanding.

- 1. Classless EIGRP . Objectives Describe the basic features of EIGRP. EIGRP is introduced to students through the informative video, Fundamental Configuration and Verification of EIGRP. After viewing the video, students should be able to explain how classless routing occurs, what is involved in auto-summarization of network addresses, and how EIGRP is configured. Students are not expected to memorize the facts from the video, as it is being viewed to introduce students to the concept of EIGRP as a distance vector routing protocol. Scenario EIGRP was introduced as a distance vector routing protocol in 1992. It was originally designed to work as a proprietary protocol on Cisco devices only. In 2013, EIGRP became a multi-vendor routing protocol, meaning that it can be used by other device vendors in addition to Cisco devices.

While viewing the video, pay close attention to the following concepts and terms: Subnet mask reporting to routing tables for classful and classless networks Auto-summarization of networks in routing tables Autonomous system numbers Wildcard masks Passive interfaces EIGRP configuration commands EIGRP verification commands Complete the reflection questions which accompany the PDF file for this activity. Save your work and be prepared to share your answers with the class. Resources Internet access Reflection 1. Explain classful routing protocols. _______________________________________________________________________________________ Classful routing protocols do not include the subnet mask in the routing update. 2. Explain classless routing protocols. _______________________________________________________________________________________ Classless routing protocols do include the subnet mask in the routing update. 3.

- 2. Classless EIGRP __________________________________________________________________ Auto-summarization allows routing tables to be reduced in size by representing several subnetted networks as one summarized network. 4. What is an autonomous system number? __________________________________________________________________ An autonomous system number is used in EIGRP configuration to define all routers belonging to a specific group to exchange EIGRP neighbor and update information. 5. What are wildcard masks? __________________________________________________________________ Wildcard masks are the inverse of subnet masks. They indicate how many hosts are available within subnets and are used as a part of the EIGRP configuration process to indicate specific, subnetted networks. 6. What is a passive interface? __________________________________________________________________ A passive interface is a network link configured to not participate in the EIGRP reporting process. 7. Is EIGRP considered a distance-vector or a link-state routing protocol? __________________________________________________________________ Like RIP, EIGRP is considered a distance vector routing protocol.
