Dynamic routing protocols

Dynamic routing protocols automate route updates, simplifying network management. They enable routers to share information about connected networks, allowing them to adapt to changes like new devices or network failures.

Routing protocols

Routing protocols are a set of rules and procedures that routers use to communicate with each other and exchange information about the network.

EIGRP

EIGRP (Enhanced Interior Gateway Routing Protocol) is a dynamic routing protocol used within an autonomous system (AS).

Components of routing protocols

Routing protocols consist of processes, messages, and algorithms. Processes define how routers interact, messages carry routing information, and algorithms determine the best path to reach a network.

Classifying IGPs

IGPs are further categorized into distance vector and link state protocols. Distance vector protocols share information with neighboring routers, while link state protocols build a complete map of the network before making routing decisions.

Classful vs Classless routing

Classful routing protocols include the subnet mask in their routing updates, while classless routing protocols do not. Classless routing protocols offer more precise network addressing.

Study Notes

  • Dynamic routing protocols are used in large networks to reduce the complexity of configuring static routes.
  • Routing protocols enable routers to exchange routing information and learn about remotely connected networks.
  • Dynamic routing protocols can be classified into categories such as EIGRP, OSPFv2, and OSPFv3.
  • Routing protocols are made up of processes, messages, and algorithms used by routers to learn about remotely connected networks.
  • Advantages of dynamic routing protocols include automatic updates and the ability to adapt to network changes.
  • Disadvantages of dynamic routing protocols include increased network traffic and potential security vulnerabilities.
  • Routing protocols can be categorized as either interior gateway protocols (IGPs) or exterior gateway protocols (EGPs) depending on whether they are used for intra-autonomous system or inter-autonomous system routing.
  • IGPs can be further classified as distance vector routing protocols or link state routing protocols.
  • Classful routing protocols don't include the subnet mask in their routing updates, while classless routing protocols do.
  • The metric and administrative distance are used to determine the best path to a network and prioritize routing sources, respectively.
