cisco ccna 200 301 en espa?ol.. Update: contains routing updates. . Query: requests neighboring routers to verify routing information. . Answer: response to the query message. If the EIGRP router does not receive an ACK for these types of packets, it will retransmit the information. After the number of retransmissions reaches 16After the number of retransmissions reaches 16, it will declare the neighbor invalid. However, the router sends the Hello packet without expecting to receive the corresponding ACKoExam Essentials EIGRP supports five types of messages: Hello, Update, Query, Answer, and Acknowledge.20.2.2 Selecting RoutesEIGRP can use the following metric components to select routes: bandwidth, latency, reliability, load, and MTU, but the default values enable bandwidth and latency (although MTU is not used by default, peers exchange it anyway). Bandwidth and latency correspond to K1 and K3.EIGRP uses bandwidth when calculating metric values, so it is critical to ensure that the bandwidth of the serial interface matches the actual speed. Cisco assumes that the serial interface is connected with a T1 connection; if this assumption is incorrect, correct it using the command bandwidth (this is discussed in Chapter 15). When specifying bandwidth values, be sure to specify them in kbit/s.Table 20.1 explains some of the important terms used by EIGRP.Table 20.1 Definitions of Important EIGRP Terminology TermsChapter 20 EIGRP Routing 529Neighbor Table Contains a list of EIGRP neighbors, similar to the adjacency relationship between the designated router/alternate designated router and other routers in a network segment in OSPF. Each of the protocols supported by EIGRP that are routed (IP, IPX, and AppleTalk) has its own neighbor table
