Which command is used to configure EIGRP?

Configuring EIGRP 1 Only two steps are required: enabling EIGRP by using the router eigrp ASN_NUMBER command. telling EIGRP which networks to advertise by using one or more network statements.

What is EIGRP configuration?

EIGRP (Enhanced Interior Gateway Routing Protocol) is an enhanced distance vector protocol that uses Diffusing Update Algorithm (DUAL) for shortest path calculation. Basic configuration enables EIGRP routing process and tells EIGRP which interfaces to include in routing process locally.

What is EIGRP protocol and how it works?

EIGRP is used on a router to share routes with other routers within the same autonomous system. Unlike other well known routing protocols, such as RIP, EIGRP only sends incremental updates, reducing the workload on the router and the amount of data that needs to be transmitted.

What are the things to configure in EIGRP routing?

How do you configure EIGRP in the Cisco IOS?

• Set the bandwidth on your interfaces using the bandwidth command.
• Start the EIGRP routing process and specify your AS number.
• Once you are through this stage, next step is to instruct the router in order to advertise the networks that are directly linked to it.

What is EIGRP named mode?

The named mode is the new way of configuring EIGRP; this mode allows EIGRP configurations to be entered in a hierarchical manner under the router mode. Each named mode configuration can have multiple address families and autonomous system number combinations.

What is EIGRP number?

EIGRP uses its own IP protocol number (88) and uses multicast packets where possible; it uses unicast packets when necessary. Communication between routers is done with multicast using the group address 224.0. 0.10 or the MAC address 01:00:5e:00:00:0a when possible.

What are two benefits of using named EIGRP configuration choose two?

EIGRP named configuration provides the following benefits: All the EIGRP configuration occurs in one location. It supports current EIGRP features and future developments. It supports multiple address families (including Virtual Routing and Forwarding [VRF] instances).

Why is EIGRP important?

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 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 command starts the EIGRP routing process?

To start an EIGRP for IPv6 routing configuration process, provide command as ipv6 router eigrp 1, where AS number is denoted as 1. The EIGRP for the IPv6 needs the 32 bit address for a router ID. Then use the command router id to configure a router ID in a router configuration mode.

What port does EIGRP use?

EIGRP has port No. 88 that runs on top of IP and is thus defined as a Transport Layer Protocol. BGP, Telnet, FTP, and other application-layer protocols lack a built-in reliability mechanism and rely on TCP (Protocol No. 6) at the Transport layer to ensure reliability.

What is leak map in EIGRP?

The leak-map just allows you to advertise a specific prefix within the range of a summary advertisement, as well as the summary itself. We can see in the diagram below that we are advertising the 10.0. 0.0/13 network out to R5 & R6, however, we are also advertising the 10.1.

What is as number in EIGRP?

Autonomous system (AS) number EIGRP uses AS numbers to enable the EIGRP process on a router. This number is only significant to the EIGRP domain as it functions as an EIGRP process ID to keep track of each EIGRP process. This is because more than one EIGRP instance can be configured on a router.

What is router ID in EIGRP?

The EIGRP router ID comes from the highest IP address assigned to a loopback interface. If no loopback interfaces are configured, the highest IP address assigned to any other active interface is chosen as the router ID. No two EIGRP routers can have the same EIGRP router ID.

What is the purpose of the EIGRP stub configuration command?

The EIGRP stub command is used with the connected and static keywords to configure the device as a stub that advertises connected and static routes.

What is EIGRP address-family?

The address-family is the “protocol” that the routing protocol supports. In this example, EIGRP supports IPv4 and IPv6. Another example is MP-BGP (Multi Protocol BGP). It supports multiple protocols: – IPv4 unicast.

What is the limitation of EIGRP?

Cons of EIGRP EIGRP is a distance vector routing protocol, and it relies on routes provided by neighbors. It does not support future applications as it is not extensible.

What is the metric of EIGRP?

EIGRP Metric = 256*(Bandwidth + Delay) Bandwidth = 10000000/bandwidth(i), where bandwidth(i) is the least bandwidth of all outgoing interfaces on the route to the destination network represented in kilobits. destination network, in tens of microseconds.

What are the four basic components of EIGRP?

EIGRP has four basic components:

• Neighbor Discovery/Recovery.
• Reliable Transport Protocol.
• DUAL Finite State Machine.
• Protocol Dependent Modules.

What are the EIGRP commands in Cisco public summary?
