Which EIGRP route is placed in the routing table?

Which EIGRP route is placed in the routing table?

The route with the lowest FD is placed in its IP routing table; this is the successor route. The FD for the chosen route becomes the EIGRP routing metric to reach that network in the routing table.

How is it identified in routing table?

Routers use Routing Tables to determine out which interface the packet will be sent. A routing table lists all networks for which routes are known. Each router’s routing table is unique and stored in the RAM of the device. The entry corresponding to the default gateway configuration is a network destination of 0.0.

What does EIGRP use to determine routes?

EIGRP determines the value of the path using five metrics: bandwidth, load, delay, reliability and MTU. EIGRP uses Five different messages to communicate with its neighbor routers. EIGRP messages are Hello, Update, Query, Reply, and Acknowledgement.

Is used to determine which route is used in the routing table?

A primary function of a router is to determine the best path to use to send packets. To determine the best path, the router searches its routing table for a network address that matches the destination IP address of the packet.

How does EIGRP determine 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. 0.0/30 network are in the topology and routing table.

What are the EIGRP tables?

EIGRP tables

• Neighbor table – stores information about EIGRP neighbors. Before exchanging routes, routers need to establish a neighbor relationship.
• Topology table – stores routing information learned from neighbor routing tables.
• Routing table – stores only the best routes to reach a remote network.

What is route Lookup?

The IPv4 Route Lookup Process When a packet arrives on a router interface, the router examines the IPv4 header, identifies the destination IPv4 address, and proceeds through the router lookup process. If the best match is a level 1 ultimate route, then this route is used to forward the packet.

Which characteristics can be used to determine if a route is an ultimate route?

Explanation: An ultimate route is a routing table entry that contains either a next-hop IP address (another path) or an exit interface, or both. This means that directly connected and link-local routes are ultimate routes.

Which two of the following are valid characteristics 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.

What is route map in EIGRP?

EIGRP supports filtering with access-lists and prefix-lists but you can also use route-maps. In this lesson I’ll show you how to use a route-map to filter in- and outbound route advertisements. We will use the following topology for this: We only need two routers for this demonstration.

What is difference between EIGRP and OSPF?

Key Differences Between EIGRP and OSPF. EIGRP is an advanced distance vector routing protocol which uses incremental and triggered updates. On the other hand, OSPF is a link-state routing protocol which resembles a map where the complete information about all the routes within that area is maintained.

Which three tables are maintained by EIGRP?

Using the DUAL, EIGRP keeps track of three 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.

What is EIGRP used for?

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.

Is EIGRP Cisco proprietary?

EIGRP is a Cisco proprietary routing protocol loosely based on their original IGRP. EIGRP is an advanced distance-vector routing protocol, with optimizations to minimize both the routing instability incurred after topology changes, as well as the use of bandwidth and processing power in the router.

What is the port number of EIGRP?

EIGRP uses port numbers within this IP protocol number to differentiate process numbers, or autonomous systems. Hence, an EIGRP process with the number 88 would send packets to the EIGRP IP protocol, unicast or multicast on 224.0.0.10, with a port number of 88.
