What is default routing in CCNA?

• Cisco CCNA Default Gateway Default Routes.
  Default route which is also known as the gateway
  of last resort, is used in forwarding packets
  whose destination address does not match any
  route in the routing table. We usually encounter
  the concept of default gateways in our daily
  computer life.

What does IP routing do?

• IP Routing 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. Data
  is routed from its source to its destination
  through a series of routers, and across multiple
  networks.

What are types of routing?

• Although there are many types of routing
  protocols, three major classes are in widespread
  use on IP networks
• Interior gateway protocols type 1, link-state
  routing protocols, such as OSPF and IS-IS.
• Interior gateway protocols type 2,
  distance-vector routing protocols, such as
  Routing Information Protocol, RIPv2, IGRP.

What is routing in networking?

• Routing Definition. Routing is the process of
  moving packets across a network from one host to
  a another. It is usually performed by dedicated
  devices called routers. Packets are the
  fundamental unit of information transport in all
  modern computer networks, and increasingly in
  other communications networks as well.
