  • Supports VLSM (subnets/supernets)
  • Integrates seamlessly with IGRP. …
  • Fast convergence.

Which among is a feature of EIGRP?

EIGRP supports the following features: Support for Classless Inter-Domain Routing (CIDR) and variable length subnet masking. Routes are not summarized at the classful network boundary unless auto summary is enabled. Support for load balancing on parallel links between sites.

What are the benefits of 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 is the purpose of EIGRP routing protocol?

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 the main difference between OSPF and EIGRP?

EIGRP vs OSPF: What’s the Difference?

Features EIGRP Protocol OSPF Protocol
CPU Requirements Lower CPU and memory needs Require high CPU and memory
Ease of Implementation Easy but no provision of auto-summary Complicated
Hierarchical Design No Yes
Convergence Time Fast Slow

Which is better OSPF or EIGRP?

The network convergence time is faster than OSPF networks, because EIGRP network can learn the topology information and updates more rapidly. The performance of packet delay variation for EIGRP is better than for OSPF.

What are the states in EIGRP?

A Passive state indicates that a route is reachable, and that EIGRP is fully converged. A stable EIGRP network will have all routes in a Passive state. A route is placed in an Active state when the Successor and any Feasible Successors fail, forcing the EIGRP to send out Query packets and re- converge.

What is RTP in EIGRP?

Reliable Transport Protocol (RTP) is responsible for guaranteed, ordered delivery of EIGRP packets to all neighbors. It supports intermixed transmission of multicast or unicast packets. For efficiency, only certain EIGRP packets are transmitted reliably.

What is EIGRP Geeksforgeeks?

Enhanced Interior Gateway Routing Protocol (EIGRP) is a dynamic routing network-layer Protocol which works on protocol number 88. EIGRP supports classless routing, VLSM, route summarization, load balancing, and many other useful features. … EIGRP exchange messages for communication between the routers operating EIGRP.

What is metric in EIGRP?

EIGRP updates contain five metrics: minimum bandwidth, delay, load, reliability, and maximum transmission unit (MTU). Of these five metrics, by default, only minimum bandwidth and delay are used to compute best path.

What is the difference between EIGRP and RIP?

RIP is a distance vector protocol. EIGRP is derived from Integrated Gateway Routing Protocol. 6. It allow maximum hop count upto 15.

What is delay in EIGRP?

Delay is the total measure of delay in the path, measured in tens of microseconds (μs). The EIGRP formula is based on the IGRP metric formula, except the output is multiplied by 256 to change the metric from 24 bits to 32 bits.

Is EIGRP scalable?

Scaling EIGRP Designs. EIGRP is tolerant of arbitrary topologies for small and medium networks. … That also may work for small-to-medium networks, up to around 200 or 300 OSPF routers. To scale EIGRP, it is a good idea to use a structured hierarchical topology with route summarization.

What is Vrrp in networking?

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts.

Which is the fastest routing protocol?

EIGRP is still the fastest protocol among all three. OSPF has a slightly longer initialization time compare to RIP and both OSPF and RIP has much longer initialization time than EIGRP.

What are LSA types?

  • Type2 is a Network LSA. …
  • Type3 is a Network summary LSA. …
  • Type4 is the ASBR summary. …

What is EIGRP topology table?

The topology table is where EIGRP stores the information for up to six alternate routes to a particular network. The backup routes are called feasible successors. The feasible successors stored in the topology table are what makes it possible for EIGRP to converge rapidly or even instantly.

What is EIGRP neighbor adjacency?

To form an EIGRP adjacency, all neighbors use their primary address as the source IP address of their EIGRP packets. Adjacency between EIGRP routers takes place if the primary address of each neighbor is part of the same IP subnet.

What is EIGRP neighbor command?

EIGRP must form a neighbor relationship before a router advertises update packets containing network prefixes. The command show ip eigrp neighbors [interface-id] displays the EIGRP neighbors for a router. Example 2-6 shows the EIGRP neighbor information using this command.

What port is OSPF?

Difference between OSPF and BGP

6. In OSPF internet protocol is used.
7. It works in 89 port number.
8. OSPF is a Link State type.
9. In OSPF Dijkstra algorithm is used.

What port is BGP?

BGP peers are established by manual configuration between routing devices to create a TCP session on port 179. A BGP-enabled device periodically sends keepalive messages to maintain the connection. Over time, BGP has become the dominant interdomain routing protocol on the Internet.

What port number does EIGRP use?

It’s a network protocol that allows routers to exchange data more quickly than prior protocols like the Interior Gateway Routing Protocol (IGRP) or the Border Gateway Protocol (BGP). EIGRP has port No. 88 that runs on top of IP and is thus defined as a Transport Layer Protocol.

What is EIGRP Auto summary?

Auto summarization is a feature which allows Enhanced Interior Gateway Routing Protocol (EIGRP) to summarize its routes to their classful networks automatically. For example, consider we are planning to use eight subnets of class B default network 172.16. 0.0/16, subnetted using a three-bit subnetting as shown below.

What is full form EIGRP?

Enhanced Interior Gateway Routing Protocol (EIGRP) is an interior gateway protocol suited for many different topologies and media.

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.

Which statement explain classless routing protocols?

Classless routing protocols do send the subnet mask with their updates. Thus, Variable Length Subnet Masks (VLSMs) are allowed when using classless routing protocols. Examples of classful routing protocols include RIPv1 and IGRP. Examples of classless routing protocols include RIPv2, EIGRP, OSPF, and IS-IS.

What is a drawback of implementing a link state routing protocol?

These protocols have a complete and synchronized picture of the overall network, therefore routing loops are very rare an difficult to occur. However these functions require more memory and processing than normal distance vector protocols.

What is feasible 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.

What are some key features of split horizon?

Split horizon is a method used by distance vector protocols to prevent network routing loops. The basic principle is simple: Never send routing information back in the direction from which it was received.

What algorithm does OSPF use?

OSPF uses the shortest path first (SPF) algorithm to determine routes that should be added to the routing table. OSPF routers maintain a map of the internetwork called the link state database.

What is the full form of BGP?

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet.

A routing protocol specifies how routers communicate with each other to distribute information that enables them to select routes between nodes on a computer network.

How EIGRP choose the best path?

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.
