eigrp Each routing protocol has its own Administrative Distance (AD), which is a value representing the trustworthiness of the specific routing protocol. If a router learns a destination route from two or more routing protocols, it selects the route from the protocol having the smallest Administrative Distance.

Administrative distance eigrp

Last Updated on April 27, 2021 by Admin. If the EIGRP summary route is set with an Administrative Distance of 90 then there is a chance that a matching route could be learned through another routing source say eBGP. eBGP's default AD is 20. Thus the Router would prefer the eBGP route over the EIGRP summary route (if the summary route was set to 90) With the summary route as 5 there is less of a chance of this situation occurring. The default administrative distance values of our popular routing protocols can be seen in the table below. The worst is RIP, with an AD value of 120. EIGRP, the most preferred IGP, has an AD of 90, and the connected interfaces will always be the most preferred with an AD value of zero.

This is because EIGRP routes have (by default) the administrative distance of 90, while RIP route have a higher 2 Jun 2013 Feasible Distance and Advertised Distance From all these views of EIGRP Advanced Concepts: EIGRP Administrative Distances – FD + AD. 1 May 2019 Since EIGRP internal routes have the best administrative distance, it's tempting to assume that the first one will be installed.

Administrative distance of EIGRP is 90, which is less than both the administrative distance of RIP and the administrative distance of OSPF, so EIGRP routes will be preferred over these routes. EIGRP uses Reliable Transport Protocol (RTP) for sending messages. EIGRP calculates its metric by using bandwidth, delay, reliability and load.

2003-05-19 Which means what EIGRP considers as a metric will never be compared to what OSPF will consider a network. So their relative differences are irrelevant. Because if a route is learned from OSPF and EIGRP, the EIGRP route will always be preferred because its Administrative Distance is lower (90 vs 110).

200 . EIGRP summary route. 5 . You can modify the administrative distance for EIGRP by using the following command Router(config-router) #distance eigrp internal-distance Router(config)#router eigrp 100. Starts the EIGRP routing process.

that is a scenario when a router learns a route via BOTH protocols, say it`s in EIGRP so the router learns the route from EIGRP and than again it learns it from OSPF as well. in this case it would choose to follow the EIGRP route because of the administrative distance values (110:90). What is the administrative distance of an external EIGRP route? Posted on April 27, 2021 by Admin Leave a comment.

eBGP's default AD is 20. Thus the Router would prefer the eBGP route over the EIGRP summary route (if the summary route was set to 90) With the summary route as 5 there is less of a chance of this situation occurring. For EIGRP, use the distance eigrp command. EIGRP assigns different administrative distance values to routes learned natively through EIGRP and to routes redistributed in from other sources. By default, natively learned routes have an administrative distance of 90, but external routes have an administrative distance of 170.

The distance can be a value from 1 to 255. … You should be able to manipulate the administrative distance of EIGRP, using the "distance eigrp" command.

An administrative distance of 170 is used for external EIGRP routes, which could be routes learned from another routing protocol and redistributed into EIGRP. More Questions: CCNA 3 (v5.0.3 + v6.0) Chapter 7 Exam Answers First (OSPF) (distance administrative par défaut - 110) et à partir de l'Interior Gateway Routing Protocol (IGRP) (distance administrative par défaut - 100), le routeur choisit l'IGRP parce qu'il est plus fiable. Ceci signifie que le routeur ajoute la version de routage de l'IGRP à la table de routage. As I understand it the router SHOULD select the eBGP route since the administrative distance is 20 for eBGP learned routes. But for some reason it is using the EIGRP learned routes with an administrative distance of 90. I can "fix" this by changing the administrative distance of EIGRP on the router to 200. But I shouldn't need to do this.
