Dynamic Routing Flashcards
What is Dynamic Routing?
Protocols is to map networks and update routing tables with the shortest routes in a fully automatic and independent manner. The method is made possible by special algorithms and protocol packets
What is a Metric?
A metric is a measurable value assigned by the routing protocol to
different routes based on the usefulness of the route. Routing protocols determine the best path based on the route with the lowest metric value.
What is RIP?
Routing Information Protocol. The RIP hop count metric will choose the path
with the least amount of hops, where hops refer to routers.
What is OSPF?
OSPF metric is based on cumulative bandwidth from source to destination. OSPF will
choose the path with the highest bandwidth.
What is EIGRP?
EIGRP (Enhanced Interior Gateway Routing Protocol) uses a metric based on minimum bandwidth, delay, load, and reliability
What is IGP?
Interior Gateway Protocols are routing protocols used within an autonomous system (AS), such as company routers.
What is EGP?
Exterior Gateway Protocols are used to map routes between autonomous systems and are mainly utilized by ISPs.
What is an autonomous system (AS)?
An autonomous system (AS) in networking is a collection of one or more associated Internet Protocol (IP) prefixes with a clearly defined routing policy that governs how the AS exchanges routing information with other autonomous systems.
What is the difference between distance vector and link state routing protocols ?
Is how the protocols discover the topology and the way they share routing information with the routers.
What is Distance Vector?
Distance vector is a routing algorithm that calculates the best path for a packet
based on the factors of distance and vector.
What is distance?
The distance between the router and the destination network, based on
the metric of number of hops (routers)
What is Vector?
The outgoing interface and the direction to the path that leads to the
destination network.
What is passive interface?
Passive interface is a feature used in all routing protocols. Its purpose is to disable routing updates on specific interfaces, which decreases resource usage and increases security.
Should passive interfaces be configured between routers?
No, Passive interfaces should not be configured between routers.
What are Classful address?
Classful routing protocols provide routing updates according to classful network addresses (A,B,C). RIPv1, IGRP
