Static Routing
A method of IP routing where the network paths are manually configured and do not change unless altered by an administrator
Dynamic Routing
A method of IP routing where the network paths are automatically adjusted
Routing Protocols
Used by routers to communicate and exchange routing information among them
IP Routing
The process of forwarding packets between networks based on IP addresses
What is a Routing Table?
A digital table stored in a router that acts as a map for network traffic
What does a router use to choose where to send a packet?
A routing table
What is a Default Route?
A route used when no specific match is found in the routing table
Major Disadvantage of Static Routing
Does not adapt to network change
Can be difficult to manage in a large network
What does RIP stand for?
Routing Information Protocol
What is RIP?
A distance vector protocol that uses hops to determine shortest path to destination based on hop count
What does OSPF stand for?
Open Shortest Path First
What is OSPF?
A link state routing protocol used to determine shortest path data to reach its destination by calculating cost based on link bandwidth
What is a Routing Metric?
A value used to determine best path
What does a low metric indicate?
A better path for data
Default Gateway
A router a device used to exit/enter a different network
When is a default gateway used?
When the destination is outside of the LAN
What is the maximum hop count for RIP?
15 hops
What is NAT
Protocol that translates private IP to a public IP before accessing the internet
Why is NAT used?
To conserve IPv4 addresses by allowing multiple devices to share the same public IP
Interior Gateway Protocol (IGP)
Used for routing within a single network/organization
Exterior Gateway Protocol (EGP)
Used for routing between different organizations/networks
Enhanced Internal Gateway Routing Protocol (EIGRP)
Hybrid dynamic routing protocol that combines both distance vector and link state protocols to choose best path
Interface
The connection point on a device that sends/receives traffic
What are the 2 main types of Dynamic Routing?
Link State
Distance Vector
What does a Routing Table Include?
Destination Network
Subnet Mask/prefix
Next Hop
Outgoing Interface
Metric
