NotepadRouters

1)Routers:

-Move data across Different Networks

+Segmentation/Subnetting

+Manage traffic flow

 

-Routers Manage tables

+Send Data where?

-Static vs Dynamic

+Protocols EIGRP,OSPF,ETC

 

-Default Gateway

+Router Only addresses Direct Packets

+Set to send to unknown Destination

 

 

2)Routing Tables

-WHere to pass on data

-Info

+Destination Network IP/SM

+Net couter get there

-Number off ”hops”

-View computer couting table

 

3) Route Print

-Protocols help detects faster path


NotepadRouting and Switching

Routing/Switching

-Allows for connecting devices

+Switching=Same Network

+Routing=Different Network

 

Understanding Devices that more that:

-HUB

-Switch

-Router

-Multilayer Switch

-Bridge

-Repeater

 

1)HUB

-Receives Data/Sends to everyone

-Computers decide to accept/reject

 

2) SWITCH

-Smart HUB

-Track MAC=PORT

 

3)MULTI-LAYER SWITCH

-Can perform routing/switching

-layer 2/3

 

4)BRIDGE

-Connect Network Segments

-Breakup/Segment traffic

 

5)REPEATER

-Increase Signal

-Amplify=Power

-SIgnal Regeneration

 


NotepadRouting Metrics

Routing Metrics

-Qualities used to determine best path

+Hop Count=>Trace Router

+MTM-Maximum transmission unit

+Lasts-Realibility,foundtrip,etc

+Latency-amount of delay on this link

 

Linkstate/Distance vector/Hybrid

 

Link state-$$ last based

-Multiple factors (Distance,speed)

-OSPF

 

DIstance Vector-Hops

-used number of hops

-RIP AND RIPV2

 

Hybrid -Both

-Distance Vector / Link State

-Use Hop Count / Cost
