How EIGRP chooses the best path through the network?

By default EIGRP uses bandwidth and delay of the line to determine the best path to a remote network. However, if desired, EIGRP can use a composite of four metrics: bandwidth, delay, reliability, and load. 0.0/30 network are in the topology and routing table.

How do I configure EIGRP and rip on the same network?

  1. Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname R2.
  2. R2(config)#router rip. R2(config-router)#version 2. R2(config-router)#network 20.0.0.0.
  3. R2(config)#router eigrp 1. R2(config-router)#network 20.0.0.0.
  4. R2(config)#interface se0/0/1. R2(config-if)#ip address 30.0.0.1 255.0.0.0.

How do I set delay in EIGRP?

The delay value used in the EIGRP metric calculation is the delay in 10’s of microseconds. So to calculate the Delay value, simply divide the DLY in the show interface command by 10. The Delay Value of 10 will be plugged into our simplified EIGRP Metric formula we derived earlier.

How EIGRP prevent routing loops?

EIGRP is a routing protocol whose strategy to prevent routing loops is based upon what is known as the EIGRP Feasibility Condition. EIGRP also makes use of another concept called Split Horizon, which we will also briefly touch on later in this article.

How do I set bandwidth in EIGRP?

To configure the percentage of bandwidth that can be used by EIGRP for IPv6 on an interface, use the ipv6 bandwidth-percent eigrp command in interface configuration mode. To restore the default value, use the no form of this command.

Which command is used to redistribute the directly connected network to other routing protocol?

2.0/24. Finally, EIGRP was configured to redistribute all ospf routes from process- ID 20, and apply a metric of 10000 (bandwidth), 1000 (delay), 255 (reliability), 1 (load), and 1500 (MTU) to the redistributed routes. RIP and IGRP also support the default-metric command.

How does EIGRP routing protocol work?

How does EIGRP work? With EIGRP, two routers form a neighbor relationship and exchange routes. Hello packets (“keepalives”) are present between the two routers; they serve to let each side know if the other goes down or if the link between them goes down.

Which routing protocol is a hybrid routing protocol?

Enhanced Interior Gateway Routing Protocol (EIGRP) is considered as a Hybrid Routing Protocol because EIGRP has characteristics of both Distance Vector and Link State Routing Protocols.

How does EIGRP measure bandwidth and delay?

Bandwidth: The bandwidth value used in the EIGRP metric calculation is determined by dividing 10,000,000 by the bandwidth (in kbps) of the slowest link along the path to the destination network. Delay: Unlike bandwidth, which represents the “weakest link,” the delay value is cumulative.

How do I change the delay and bandwidth in EIGRP?

Since the BANDWIDTH command can end up impacting a lot of other configurations (like QoS), we can use the DELAY command to manipulate EIGRP metrics (and therefore, paths) without having to touch the BANDWIDTH command. Enter configuration commands, one per line. End with CNTL/Z. R1(config-if)#delay?

What is EIGRP in Cisco router?

EIGRP (Enhanced Interior Gateway Routing Protocol), is a Cisco Proprietary Hybrid Routing Protocol. The configuration of EIGRP is similar to other Routing Protocols. In this example, we will configure EIGRP on Packet Tracer with Cisco Routers..

What is the default EIGRP administrative distance for routing protocols?

91 is chosen because it is 1 greater than the default EIGRP administrative distance for internals (which is 90). The default administrative distance for EIGRP externals (routes redistributed into EIGRP) is 170. Refer to the in the document for the default values of all routing protocols.

How does EIGRP authentication work?

Enhanced Interior Gateway Routing Protocol (EIGRP) authentication is configurable on a per-interface basis; packets exchanged between neighbors connected through an interface are authenticated. EIGRP supports message digest algorithm 5 (MD5) authentication to prevent the introduction of unauthorized information from unapproved sources.

What topology will you use for your EIGRP config example?

For our EIGRP Config Example, we will use the below topology consist of four routers and four PCs on Packet Tracer. You can DOWNLOAD the Cisco Packet Tracer example with .pkt format at the End of This Lesson.
