Is EIGRP on CCNA?
EIGRP is not explicitly listed in the latest 200-301 version of the CCNA exam topics (whereas OSPF is) but you can still be tested on it in the exam.
What is EIGRP used for?
Enhanced Interior Gateway Routing Protocol (EIGRP) is a network protocol that enables routers to exchange information more efficiently than earlier network protocols, such as Interior Gateway Routing Protocol (IGRP) or Border Gateway Protocol (BGP).
What is EIGRP on Cisco router?
EIGRP is a Cisco proprietary routing protocol based on their original Interior Gateway Routing Protocol. EIGRP can only be used on networks where all routers are Cisco routers. The administrative distance for EIGRP is 90 and 170 for internal and external EIGRP, respectively.
What is the EIGRP algorithm?
EIGRP uses a diffusing update algorithm (DUAL) to identify network paths and provides for fast convergence using precalculated loop-free backup paths. Most distance vector routing protocols use hop count as the metric for routing decisions.
What is OSPF in CCNA?
OSPF (Open Shortest Path First) is a link state routing protocol. Because it is an open standard, it is implemented by a variety of network vendors. OSPF will run on most routers that doesn’t necessarily have to be Cisco routers (unlike EIGRP which can be run only on Cisco routers).
What devices run using EIGRP?
EIGRP is used on a router to share routes with other routers within the same autonomous system.
Why is OSPF preferred over EIGRP?
The scalability of the OSPF is higher than EIGRP because EIGRP is complicated and vendor-specific and incapable of migrating from one vendor to the other. Conversely, OSPF is an open standard and simple protocol through which the network can be scaled easily.
Does CCNA use EIGRP as its IGP?
CCNA.com has a small network that is using EIGRP as its IGP. All routers should be running an EIGRP AS number of 12. Router MGT is also running static routing to the ISP. CCNA.com has recently adding the ENG router. Currently, the ENG router does not have connectivity to the ISP router.
What is the default EIGRP number for lab simulation?
Lab Simulation Question – EIGRP. CCNA.com has a small network that is using EIGRP as its IGP. All routers should be running an EIGRP AS number of 12. Router MGT is also running static routing to the ISP.
What is the EIGRP protocol?
This protocol is an evolution of an earlier Cisco protocol called IGRP, which is now considered obsolete. EIGRP supports classless routing and VLSM, route summarization, incremental updates, load balacing and many other useful features.
What does the “network …” command in EIGRP do?
The “network …” command in EIGRP (and OSPF, RIP) does not means “advertise this network” but means “If I has interface (s) belongs to this network please turn on EIGRP on that interface. Therefore when you don’t use wildcard mask EIGRP will turn on EIGRP on all interfaces that belongs to the network you specify in the “network …” command.
