FAQ: What Is Eigrp Neighbor?

What needs to match for EIGRP neighbors?

Two routers must use same K Values in order to become the EIGPR neighbor. For example if one router is using three K- Values (K1, K2 and K3) while second router is using default K values (K1 and K3) then these two routers will never become neighbor. In order to become EIGRP neighbor two routers must use same K values.

What is the purpose of the EIGRP neighbor and topology tables?

neighbor table The neighbor table holds a list of all the routers EIGRP has established a neighborship with. topology table The topology table keeps track of the entire network topology. It stores all the information about all the routes that the router has received from its neighbors, even duplicate routes.

How do I check my neighbors EIGRP?

In order to verify this, enter the debug eigrp packet hello command. As an alternative to the use of the debug command, you can ping IP address 224.0. 0.10 and verify whether that neighbor replies.

What is EIGRP and how does it work?

Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. EIGRP is used on a router to share routes with other routers within the same autonomous system.

What is the maximum hop count for EIGRP?

Similar to its predecessor IGRP, EIGRP has a maximum hop count of 224 and a default maximum hop count of 100. EIGRP has administrative distance of 90. This means its routes are slightly more trusted than IRGP routes and a lot more trusted than RIP routes that have an administrative distance of 120.

Do EIGRP timers have to match?

Such a configuration reinforces the point that EIGRP neighbors do not require matching timers (although it’s a best practice to have matching timers). The following example shows this timer configuration for routers R1 and R2.

What does EIGRP stand for?

Enhanced Interior Gateway Routing Protocol (EIGRP) – Cisco.

What is reported distance in EIGRP?

Feasible distance (FD) – the metric of the best route to reach a network. That route will be listed in the routing table. Reported distance (RD) – the metric advertised by a neighboring router for a specific route. It other words, it is the metric of the route used by the neighboring router to reach the network.

How do I check EIGRP?

Issue the show ip route eigrp command to verify. Issue the show ip eigrp topology command to verify. If routes are not seen in the topology table, issue the clear ip eigrp topology command. Issue the show ip eigrp topology net mask command, to find the Router ID (RID).

What is true EIGRP?

Explanation: EIGRP stands for Enhanced Interior Gateway Routing Protocol is a routing protocol designed by Cisco. It is available only on Cisco routers. Explanation: EIGRP metric is K-values which are integers from 0 to 128. They are used to calculate the overall EIGRP cost with bandwidth and delay metrics.

What does show ip EIGRP neighbors do?

Use the show ip eigrp neighbors command to determine when neighbors become active and inactive. It is also useful for debugging certain types of transport problems.

What is an advantage of using EIGRP?

Benefits of EIGRP It makes use of link more effectively through (ECMP) Equal-Cost Multi-Path and unequal cost load sharing. It performs a much easier transition with a multi-address family. It supports both IPV4 and IPV6 networks. It provides encryption for security and can be used with iBGP for WAN routing.

What are three features of EIGRP?

The characteristics of EIGRP follow:

  • Hybrid routing protocol (distance vector that has link-state protocol characteristics).
  • Uses IP protocol 88.
  • Classless protocol (supports VLSMs).
  • Default composite metric uses bandwidth and delay.
  • You can factor load and reliability into the metric.

Which is better EIGRP or OSPF?

EIGRP vs OSPF: Scalability. 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.
