Block 6/ 2A Flashcards
(46 cards)
Special static ROUTE manually defined by the system administrator as the path to take when no ROUTE to the destination is known.
Default ROUTES
Manually defined by the system administrator as the only path to the destination.
Useful for controlling security and reducing traffic
Static Routes
__________ is another name for a default route. Router to which all non-routable packets are sent
Gateway of Last Resort
__________ is defined as a network that is NOT listed in a router’s routing table.
Non-Routable
A ___________ is a NETWORK LAYER protocol that exchanges information packets with otter inter work routers in order to build and maintain a routing table.
Dynamically learned routes (Routing Protocol)
List some common metrics:
Path length Reliability Delay Bandwidth Load Communication cost
______ is the MOST COMMON routing metric.
Sum of the costs associated with each link traversed.
Path length
Metric that specifies the number of passes through internetworking devices, such as routers.
Hop Count
_______ refers to the dependability of each network link.
Reliability
_____ refers to the length of time required to move a packet from source to destination through the internetwork.
Delay
_____ is a conglomeration of several important variables. Common and useful metric.
Delay
Refers to the available traffic capacity of a link.
Bandwidth
____ refers to the degree to which a network resource, such as a router, is busy
Load
Metric that is set by the Network Administrator
Communication Cost
_______ __________ initialize and maintain routing tables.
Routing Algorithms
What are the classification of algorithms?
Single-Path or Multi-Path
Flat or Hierarchical
Intra-domain or Inter-domain
Distance vector or Link state
_____ ____ algorithms send packets to a destination using the same or SINGLE PATH unless there is a topology change that affects the available route.
Single-Path algorithms
_____ ____ algorithms support multiple paths to the same destination by LOAD BALANCING or load sharing.
Multi-Path algorithms
____ algorithms in a flat routing system, the routers are peers of all others.
Sometimes referred to as “Classful” routing
Flat algorithms
____________ algorithms is called “Classless” routing and supports Variable Length Subnet Masks (VLSM).
Hierarchical algorithms
____________ ______ Routing system that often designates logical groups of nodes, called domains, autonomous systems, or areas.
Hierarchical System
Work only within a routing domain and are used with Interior Gateway Protocols.
Intra-domain algorithms
______-_______ algorithms are used with EXTERIOR Gateway Protocols (EGP).
Inter-Domain Algorithms
_____-______ algorithms exchange routing information within and between Autonomous System such as on the internet
INTER-domain algorithms
