Routing Protocols Flashcards
(Looping interface) A loopback interface is a fake or virtual interface that is created on a ______.
router
(Looping interface) is not a physical interface; it’s ______. This virtual interface is assigned an __ _______ of your choice.
virtual, IP, address
(Looping interface) The purpose of a loopback interface is for _______ and _____________ purposes.
testing, administration
(Routing Table) A routing table is a file that contains a set of _____ that show information on what path a data packet takes to its __________.
rules, destination
(Routing Table) a router uses _______ ______.
routing tables
(Routing Table) as a data packet arrives at the router, the router looks at its _______ _____ to find out where to forward the ____ ______ along the best path to its destination.
routing, table, data, packet
(Routing Table) A basic routing table contains:
-Network destination
-Subnet mask
-Gateway
-Interface
-Next hop
-Metric
(Routing Table) Network destination: the IP address of the _____ __________
final destination
(Routing Table) Subnet mask: determines which part of the IP address is the ____ and _______ portion
host, network
(Routing Table) Gateway: tells the router which __ _______ the data packet should be ___________ to
IP, address, forwarded
(Routing Table) Interface: the outgoing IP address of the _____ that’s sending the ____.
device, data
(Routing Table) Next hop: the IP address to which the IP address is __________.
forwarded
(Routing Table) Metric: determines the best _____ among multiple ____________.
route, destinations
(Routing protocols) Routing protocols collect information about the current ________ ______ and map out the best path for data packets to take to their specific ___________.
network, status, destination
there are three different types of routing protocols:
-Distance Vector
-Link State
-Hybrid
there are three different types of routing protocols:
-Distance Vector
-Link State
-Hybrid
Distance vector: These protocols factor in the distance to the destination based on how many hops. A hop refers to how many routers a data packet has to go through to reach its destination.
One of the distance vector protocols is called RIP, which stands for Routing Information Protocol.
Routers that use RIP broadcast their routing information to other routers every 30 seconds, regardless if the routing information has changed or not.
developers created RIP version 2, which solved the problem of _________ broadcast traffic that RIP version 1 caused.
excessive
another distance vector routing protocol is called BGP which stands for ______ _______ ________
border, gateway, protocol
(BGP) and this is the standard _______ ________ of the internet, it determines routing directions that are based on paths and policies.
routing, protocol
Link state is a routing protocol that is used by routers to share __________ and independently map out the best path on a _______.
information, network
Two examples of link state protocols are OSPF (____ ________ ____ _____) and ISIS (__________ ______ __ ___________ ______).
-Open Shortest Path First
-Intermediate System to Intermediate System
(OSPF) is used to determine the correct route for ____ ________ to take to their destination.
data, packets
(OSPF) It collects information from other routers using __ and creates a topology map of the _______.
IP, network
ISIS, organizes routers into _______, meaning that the routers are organized into ______, and this is how ISIS primarily functions within these domains.
domains, groups
(ISIS) Unlike OSPF, which uses IP to communicate, ISIS uses CLNS instead, which is a ____________ _______ _______.
Connectionless, network, service
(Hybrid) In this case, we’re talking about EIGRP (__________ ________ _______ _______ ________).
Enhanced, Interior, Gateway, Routing, Protocol
(EIGRP) It is a combination of ________ ______ and ____ _____ protocols and only runs on Cisco routers.
distance, vector, link, state
(EIGRP) It is ____, has less overhead, and can support many _______ _____ protocols.
fast, network, layer
SIP stands for _______ ________ ________, and this protocol is used for establishing communication sessions over the internet.
Session, Initiation, Protocol
(SIP) Voice over IP (VoIP), which is a term used for _____ _______________ over __ ________.
Voice, Communications, IP, networks
(SIP) For example, VolP, also uses SIP. It is also used for services such as _______ _________ and ___________.
instant, messaging, conferencing
(SIP) SIP operates at the __________ _____ in the OSI model.
application, layer
RTP stands for ?
Real-Time Transport Protocol
(RTP) is the internet standard for transporting real-time data, such as streaming _____ and _____.
audio, video
RTP is often used over UDP, so it doesn’t guarantee ____ ________.
data, delivery
RTP is also used with RTCP (Real-Time Transport Control Protocol), which enables you to monitor the _______ of the ____ being delivered.
quality, data
RTP can be used to send data in both u_______ and m________.
unicast, multicast
Distance vector: These protocols factor in the distance to the destination based on how many ____. A hop refers to how many _______ a data packet has to go through to reach its __________.
hops, routers, destination
One of the distance vector protocols is called RIP, which stands for _______ ___________ _______.
Routing, Information, Protocol
Routers that use RIP broadcast their _______ __________ to other routers every __ seconds, regardless if the routing information has changed or not.
routing, information, 30
