Lesson 13: Routing Protocols Flashcards
(46 cards)
These protocols have
been designed to allow the exchange of _____________, or known networks, between routers.
Routing tables
Specifies the direction of the next-hop router or exit interface to reach
the destination
Vector
One of the oldest distance-vector routing protocols which
employ the hop count as a routing metric.
Routing Information Protocol (RIP)
Who developed Enhanced IGRP (EIGRP) in the early 1990s to overcome limitations of RIP and its own IGRP.
“Cisco”
ACRONYM: IS-IS
Intermediate System to Intermediate System
It is the process of moving packets across a network from one host to another and selecting best paths in a network.
Routing
This happens automatically using routing protocols
Dynamic routing
Was developed in the mid-1980s as a Cisco proprietary protocol to help overcome some of limitations of RIP,
such as the single metric of hop count.
Interior Gateway Routing Protocol
ACRONYM: AS
Autonomous System
It contains route information both from directly connected
external peers, as well as internal peers, and continually updates the routing table as
changes occur.
Routing Information Base (RIB)
Commonly referred to as balanced-hybrid routing, is a
combination of distance-vector routing, which works by sharing its knowledge of the entire network with its neighbors and link-state routing which works by having the routers tell every router on the network about its closest neighbors.
Hybrid Routing
Used to achieve fast
convergence for internal routes, including IP addresses of BGP routers.
Internal routing protocol
One of a family of IP Routing protocols, and is an Interior
Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network.
Open Shortest Path First (OSPF)
Examples of Distance Vector Routing:
- RIP (routing information protocol)
- IGRP (interior gateway routing protocol)
An Interior Gateway Protocol that uses packet-switched networks to support efficient autonomous system routing for Internet service providers and large enterprises.
Intermediate System to Intermediate System (IS-IS)
It determines how your data gets to its destination and
helps to make that process as smooth as possible.
Routing protocols
ACRONYM: OSPF
Open Shortest Path
First
A generic term that refers to a formula, orprotocol, used by arouterto determine the appropriate path over which data is transmitted.
Routing Protocol
Examples of Link State Routing:
- Open Shortest Path First (OSPF)
- Intermediate System to Intermediate System (IS-IS)
Prevents routing loops by
implementing limit on the number of hops allowed in a path from source to
destination”.
Routing Information Protocol (RIP)
ACRONYM: SPF
Shortest Path First
Identifies how far it is to the destination network and is based on a metric such as the hop count, cost, bandwidth, delay, and more
Distance
It is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems
(AS) on the Internet.
Border Gateway Protocol (BGP)
It is the protocol used throughout the
Internet to exchange routing information between networks. It is the language spoken by routers on the Internet to determine how packets can be sent from one router to another to reach their final destination.
Border Gateway Protocol (BGP)
