ccna 200 301 syllabus plural form of fox.OSPF (Open Shortest Path First), an internal gateway protocol developed by the IETF (Internet EngineeringTaskForce), was created in the mid-1980s when RIP became unsuitable for interconnecting large-scale heterogeneous networks. It is a routing protocol developed for IP networks by the IETF (Internet EngineeringTaskForce) Internal Gateway Protocol working group. OSPF is a link-state based routing protocol that requires each router to send link-state announcement information to all other routers in its same administrative domain. Included in OSPF's link-state announcements are interface information, metric values, and a number of other variables. A router running OSPF must first collect allall link state information and use the SPF algorithm to figure out the shortest path to each node, using this router as the root. The OSPF protocol is described in Chapter 8 of this book.3. IS-IS IS-IS (IntermediateSystem-to-IntermediateSystem) is an ISO standard protocol that is used in conjunction with Connectionless Network Service (CLNS) and other ISO routing protocols. It is used in conjunction with Connectionless Network Service (CLNS) and other ISO routing protocols. IS-IS is also a link stateThe protocol, which uses the SPF algorithm to calculate the best path to each network. This protocol is less commonly used in China and is more commonly found in the United States on carrier networks, excluding IS-ISo from the CCNA exam.IGRP (Interior Gateway Routing Protocol) is also a distance vector routing protocol, which is Cisco's proprietary routing protocol.It is a Cisco proprietary routing protocol that uses composite metrics (including latency, bandwidth, load, and reliability). This routing protocol is older and largely retired from the history books and from the CCNA exam. 5.5. EIGRP EIGRP (EnhanceIGREP, enhanced IGRP) is an upgraded version of IGRP and a Cisco proprietary routing protocol. EIGRP combines the advantages of distance vector and link-state routing protocols with faster convergence, and the algorithm used is DUAL (Diffiising Update Algorithm,(Diffiising Update Algorithm). The EIGRP protocol is described in Chapter 7 of this book.6. BGPWhile the previous five protocols are all IGP protocols, BGP is an EGP designed for the TCP/IP Internet and is used between multiple autonomous systems. It is neither a pure link state algorithm nor a pure distance vector algorithm, each autonomous system can run different internal gateway protocols, and different autonomous systems exchange network reachable information through BGP. BGP is part of CCNP and is not required in CCNA.
