How can I use only one path when a router has two equal cost paths?
How can I use only one path when a router has two equal cost paths? A. Configure the bandwidth value on the interfaces to default, and increase the delay on the backup interface so that the router does not see two equal cost paths.
What is EIGRP protocol and how it works?
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.
When two or more routes to the same destination are learned from different routing protocols What does a router use to choose between the routes?
Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols.
How does a router choose between two routes to the same destination network?
Whenever multiple paths to the same network exist, each path uses a different exit interface on the router to reach that network. The best path is selected by a routing protocol based on the value or metric it uses to determine the distance to reach a network.
Which parameter does the router use to select the best path?
If there are two or more possible routes to the same destination, the metric is used to decide which route appears on the routing table. The lower the metric, the better the route.
Is IGRP still used?
EIGRP adds support for VLSM (variable length subnet mask) and adds the Diffusing Update Algorithm (DUAL) in order to improve routing and provide a loopless environment. EIGRP has completely replaced IGRP, making IGRP an obsolete routing protocol. In Cisco IOS versions 12.3 and greater, IGRP is completely unsupported.
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.
What are the four components of EIGRP?
EIGRP has four basic components:
- Neighbor Discovery/Recovery.
- Reliable Transport Protocol.
- DUAL Finite State Machine.
- Protocol Dependent Modules.
What metric is used by OSPF to determine the best path?
OSPF is a link-state routing protocol which uses cost as a metric for optimal path calculation. It is an open standard protocol based on Dijkstra’s Shortest Path First ( SPF ) algorithm.
What are two functions of a router choose two?
Explanation: Routers connect multiple networks, determine the best path to send packets, and forward packets based on a destination IP address.
Which parameter does the router use to choose the path to the destination?
If there is a route for the destination network in the routing table, the router forwards the packet using that information. If there are two or more possible routes to the same destination, the metric is used to decide which route appears on the routing table.
Is there a second route in EIGRP routing table?
Currently traffic is using only interface GigabitEthernet0/1. A second route, not in the routing table, is available with a metric of 264000. What value is needed in the variance command to make EIGRP put the second route into the routing table?
Can a learned route be installed in the local routing table?
Any EIGRP-learned route with a metric equal to 3 times the successor metric will be installed in the local routing table. The network statements require subnet masks to prevent autosummarization. 12.
How to configure a router with EIGRP?
The networks that are configured on serial 0/0/0 and serial 0/1/0 of router R1 are overlapping. The passive-interface command should have been issued on serial 0/1/0. 6. By default, how many equal-cost routes to the same destination network will EIGRP install in the routing table? 7. Open the PT Activity.
How does a Cisco router choose which route to use?
One of the intriguing aspects of Cisco routers, especially for those new to routing, is how the router chooses which route is the best among those presented by routing protocols, manual configuration, and various other means.
