|
Definition
the process of directing packets between networks or subnets |
|
|
Term
|
Definition
when each router uses entries in a routing table, as well as various metrics |
|
|
Term
|
Definition
route discovery operations to build and update routing tables themselves |
|
|
Term
|
Definition
administrators manually add routing entries to configure files, which routers load when they start up |
|
|
Term
dynamic routing is useful, especially in |
|
Definition
larger network environments |
|
|
Term
advantage of dynamic routing |
|
Definition
if a network suffers from a router or link failure routers can automatically detect the problem and advertise that the affected route or routes are no longer valid |
|
|
Term
|
Definition
is the state of router on a internetwork that all have the same, consistent topology and route information |
|
|
Term
|
Definition
time for a set of routers to recover to a consistent view of the internetworks after the topology change |
|
|
Term
|
Definition
each router passes a copy of its routing table to its neighbors, and maintains a table minimum distances to every node |
|
|
Term
routing information protocol (RIP) |
|
Definition
selects the one with the lowest metric |
|
|
Term
alternatives to the distance-vector routing |
|
Definition
link-state routing and path-vector routing |
|
|
Term
|
Definition
keeps track of the routes from itself to each data destination |
|
|
Term
instead of recording a route to each individual node, path vector routing can treat an entire autonomous system, as ? |
|
Definition
|
|
Term
Border or exterior routers |
|
Definition
pass routing information to the next AS in a chain. |
|
|
Term
|
Definition
broadcast small updates, and converge quickly |
|
|
Term
example of the link-state protocol is |
|
Definition
Open Shortest Path First (OPSF) protocol |
|
|
Term
both distance-vector and link-state routing use |
|
Definition
|
|
Term
routing Information protocol (RIP) |
|
Definition
a distance-vector routing protocol that's easy to configure, works well in simple autonomous systems, and is best deployed in small business |
|
|
Term
|
Definition
enhances RIP by supporting the following features: —Next Hop Addressing: —Authentication: —Subnet mask: —Multicast addressing: |
|
|
Term
border gateway protocol (BGP) |
|
Definition
is a path-vector routing protocol used to established routing between internet service provides (ISPs). |
|
|
Term
Interior gateway routing protocol (IGRP) |
|
Definition
distance-vector protocol routing protocol developed by Cisco to improve RIP and RIPv2 |
|
|
Term
Enhanced Interior Gateway routing protocol (EIRGP) |
|
Definition
considered a hybrid protocol. it includes features that support VSLM, and both classful and classless subnet mask |
|
|
Term
Open Shortest Path First (OSPF) |
|
Definition
this router uses the information in its database to build the shortest possible path to each destination on a network |
|
|
Term
Intermediate system to intermediate system (IS-IS) |
|
Definition
a link-state protocol, support more router than OSPF and doesn't require that a specific type of network address be used |
|
|
Term
|
Definition
occurs if two routers identify one another as the next point in a path to a particular destination |
|
|
Term
|
Definition
is a content-based network on which a group of nodes are allowed to compete with each other for media access |
|
|
Term
|
Definition
logical area in a computer network, where any node connected to the computer network can directly transmit to any other node in the domain without having to go through a central routing device |
|
|
Term
|
Definition
specify how routers communicate with one another and how they share information on network topology and available routes |
|
|
Term
IGP (interior gateway protocol) |
|
Definition
routing protocols that govern the exchanged of routing information between routers within an autonomous system |
|
|
Term
|
Definition
is a self-contain network of routers and devices |
|
|
Term
EGP (exterior gateway protocol) |
|
Definition
routing protocols that handle the exchanged of routing information between autonomous system. |
|
|
Term
|
Definition
collection of networks under one administrative control that has a define routing policy |
|
|
Term
two main categories of IGPs |
|
Definition
distance-vector protocols, and link-state protocols |

Term
examples of distance - vector protocols |
