Routing
OSI network layer protocol defines the following features:
3 features |
|
Definition
- Routing:
- The process of forwarding packets (Layer 3 PDUs).
- Logical addressing:
- Addresses that can be used regardless of the type of physical networks used, providing each device (at least) one address.
- Logical addressing enables the routing process to identify a packet’s source and destination.
- Routing protocol:
- A protocol that aids routers by dynamically learning about the groups of addresses in the network, which in turn allows the routing (forwarding) process to work well.
- Other utilities:
- The network layer also relies on other utilities.
- For TCP/IP, these utilities include Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Address Resolution Protocol (ARP), and ping

What is a Routing protocol? |
|
Definition
- A routing protocol learns routes and puts those routes in a routing table
- In most cases, routers build their routing table entries dynamically using a routing protocol.
- Routing protocols learn about all the locations of the network layer “groups” in a network and advertise the groups’ locations
- As a result, each router can build a good routing table dynamically.
- Routing protocols define message formats and procedures, just like any other protocol.
- The end goal of each routing protocol is to fill the routing table with all known destination groups and with the best route to reach each group
