Routing/Switching Flashcards
Collision Domain
Network/segment where a collision can occur. Nodes contend for access to the same physical medium
Microsegmentation
Divides a network with switches so only two nodes exist in each collision domain. 24 port switch = 24 collision domains
Broadcast domain
Network/segment where nodes can directly transmit to any other node in the area with no central routing device
STP
Spanning Tree Protocol
Where is STP located in OSI model?
Layer 2
What does STP do?
Prevents switching loops
RSTP
Rapid Spanning Tree Protocol. 802.1w
Packet-Switched network
Data broken into packets that move in sequence, and takes best route available. Contains all necessary info to get from one endpoint to another and is reassembled after
Circuit switching
One endpoint creates single connection to other endpoint. When established, data transmits as long as circuit is active. Bandwidth dedicated until no longer needed
Distributed Switching
Centralized switch connects and managed remotely deployed switches in hierarchal configuration
Distance-Vector routing
Routers calculate distance/direction between two points and route packets based on fewest number of hops. “How far” and “in what direction”
Link-state routing
Floods routing info to all router to build/maintain more complex network route database
Hybrid routing
Both distance-vector and link-state combined
Path-vector routing
Interdomain routing. Router keeps track of route from itself to destination
What are some distance vector protocols?
RIP - Routing Information Protocol which is classful
RIPv2 - classless
RIPng - next generation, used for IPv6
