Chapter 9 Flashcards
Is a tool used by routers to dynamically find all the net works in the internetwork as well as to ensure that all routers have the same routing table. p278
Routing protocol
What are the four routing protocols. p278
(RIP) Routing Information Protocol
(RIPv2) Routing Information Protocol version 2
(EIGRP) Enhanced Interior Gateway Routing Protocol
(OSPF) Open Shortest Path First
To be capable of routing packets, a router must know at least the following information: p279
Destination address
Neighbor routers from which it can learn about remote networks
Possible routes to all remote networks
The best route to each remote network
How to maintain and verify routing information
router learns about remote networks from neighbor routers or from an administrator. The router then builds a________(a map of the internetwork) that describes how to find the remote networks. p279
routing table
If a network isn’t directly connected to the router, the router must use one of two ways to learn how to get to it. p279
static routing
dynamic routing
which can be a ton of work because it requires someone to hand-type all network locations into the routing table. p279
static routing
a protocol on one router communicates with the same protocol running on neighbor routers. p279
dynamic routing
MAC addresses are always local on the LAN and always go through and past a router. true or false p282
false
At the end of the frame is something called a ________field that houses the result of the cyclic redundancy check (CRC). p282
Frame Check Sequence (FCS)
IP does not run a complete CRC the way the Data Link layer does—it only checks the________ for errors. p285
header
is a collection of networks or subnets that are in the same administrative domain. p290
autonomous system
(BGP) stands for what. p290
Border Gateway Protocol (BGP)
