IP Routing (Lesson 1) Flashcards
is an umbrella term for the set of protocols that determine the path that data follows in order to travel across multiple networks from its source to its destination.
IP Routing
NAT stands for…?
Network Address Translation
It’s a way to map multiple private addresses inside a local network to a public IP address before transferring the information onto the internet.
NAT Network Address Translation
NAT Types (5)
- Static NAT
- Dynamic NAT
- Port Address Translation (PAT)
- Routing Information Protocol (RIP)
- Interior Gateway Routing Protocol (IGRP)
When the local address is converted to a public one, this NAT chooses the same one.
A consistent public IP address associated with that router or NAT device.
Static NAT
Instead of choosing the same IP address every time, this NAT goes through a pool of public IP addresses.
Getting a different address each time the router translates the local address to a public address.
Dynamic NAT
It’s a type of dynamic NAT, but it bands several local IP addresses to a singular public one.
Port Address Network (PAT)
is a distance-vector routing protocol.
Routers running the distance-vector protocol send all or a portion of their routing tables in routing-update messages to their neighbors.
Routing Information Protocol (RIP)
isa distance vector interior gateway protocol developed by Cisco.
It is used by routers to exchange routing data within an autonomous system.

Features of RIP (4)
(Possible Question? idk)
- Updates of the network are exchanged periodically.
- Updates are always broadcasting
- Full routing tables are sent in updates.
- Routers always trust routing information received from neighbor routers.

Basic Router Troubleshooting Commands (6)
- show running_config
- show interfaces
- show ip_route
- ping IP_ADDRESS
- traceroute IP_ADDRESS
- debug command
This command is used to enter enable mode.
enable
duh
This command is used to enter global configuration mode, which allows you to make changes to the router’s global configuration.
configure terminal
This command is used to enter interface configuration mode, which allows you to make changes to a specific interface on the router.
interface interface_name
This command is used to set the hostname of the router.
hostname hostname
This command is used to configure the IP address and subnet mask of an interface.
ip address IP_ADDRESS
SUBNET_MASK
meron _ yung gita ng IP at Address and yung Subnet at Mask
This command is used to enable an interface that has been previously shut down.
no shutdown
This command is used to exit the current configuration mode and return to the previous mode.
exit
This command is used to exit configuration mode and return to privileged mode.
end
This command is used to display the current configuration of the router.
show running_config
This command is used to display information about all of the interfaces on the router, including their status, IP address, and bandwidth usage.
show interfaces
This command is used to display the routing table of the router, which shows the paths that packets take to reach their destination.
show ip_route
This command is used to test the connectivity between the router and a specific IP address.
ping IP_ADDRESS
This command is used to trace the path that packets take to reach a specific IP address, and to identify any issues along the way.
traceroute IP_ADDRESS
This command is used to enable debugging for a specific function, such as routing or authentication.
debug command
