SEMESTER 2 Chapter 9 EIGRP V 4.0 9.0.1 What features are found in EIGRP that are not found in other distance vector routing protocols? Reliable Transport Protocol (RTP) Bounded Updates Diffusing Update Algorithm (DUAL) Establishing Adjacencies Neighbor and Topology Tables What type of protocol does EIGRP act like? Link-state What type of routing protocol is EIGRP? Distance Vector How is EIGRP similar to RIP v2? EIGRP can operate with classful or classless routing behavior 9.1.1 What protocol was the precursor to EIGRP? IGRP What are the metrics composed of? bandwidth, delay, reliability, and load What algorithm was used in IGRP? the Bellman-Ford algorithm What two things does EIDRP not do? EIGRP does not send periodic updates and route entries do not age out. What table does EIGRP maintain that is separate from the routing table? Topology table What is included in the above table? includes both the best path to a destination network and any backup paths that DUAL has determined to be loop-free Define loop-free. the neighbor does not have a route to the destination network that passes through this router What is the result of using mechanisms to prevent routing loops and count to infinity problems in RIP and IGRP? Slow convergence What does EIGRP use to solve these problems? loop-free paths are achieved through a system of route calculations (diffusing computations) that are performed in a coordinated fashion among the routers 9.1.2 What are the three type/length/ value types in EIGRP? EIGRP Parameters, IP Internal Routes, and IP External Routes What is the protocol field value for EIGRP? 88 What is the destination ip address? 224.0.0.10 What is the MAC address for an EIGRP packet in a frame? 01-00-5E-00-00-0A 9.1.2.2 What are the four Opcodes for EIGRP? EIGRP Parameters, IP Internal Routes, and IP External Routes

What are the two factors that EIGRP weights? Bandwidth and delay Define delay. the sum of delays from source to destination in units of 10 microseconds Define Bandwidth. the lowest configured bandwidth of any interface along the route What is the minimum length for a subnet mask in EIGRP? 24 What is added to the subnet mask to reach the minimum length? Zeros 9.1.3 What are the three protocols does EIGRP support? IP, IPX, and AppleTalk What does EIGRP use to be able to support these protocols? protocol-dependent modules (PDM) 9.1.4 What protocol does EIGRP use to deliver and receive packets? used by EIGRP for the delivery and reception of EIGRP packets Why does EIGRP have to use the above protocol? EIGRP was designed as a Network layer independent routing protocol; therefore, it cannot use the services of UDP or TCP because IPX and Appletalk do not use protocols from the TCP/IP protocol suite. What are the two methods of
