Questions and Answers

What is IP Routing?

  • The process of broadcasting a packet from its source to all devices in the network
  • The process of sending a packet from its source to its destination through a switched network
  • The process of filtering packets based on their source and destination addresses
  • The process of forwarding a packet from its source to its destination through a routed network (correct)

    • What is the purpose of a Routing Protocol?

  • To transfer information learned by each router to other routers to build the routing table (correct)
  • To encrypt the data being transferred between routers
  • To monitor the network traffic
  • To authenticate the routers in the network

    • What is OSPF?

  • A Routed Protocol that is used to transfer information between routers
  • A Routing Protocol that forwards packets based on the number of hops
  • A Routing Protocol that selects the best path to transfer information between routers (correct)
  • A Hybrid Routing Protocol that combines Static and Dynamic Routing

    Study Notes

    IP Routing and OSPF Protocol

    • IP Routing is the process of forwarding a packet from its source to its destination through a routed network.
    • Routing Protocol, such as RIP and OSPF, is used to transfer information learned by each router to other routers to build the routing table.
    • OSPF is a Routing Protocol that selects the best path to transfer information between routers.
    • Routed Protocol refers to IP packets that are routed between the routers, such as IPv4 and IPv6.
    • Autonomous System is a collection of devices under the same administrative authority.
    • There are three types of Routing Protocol: Static Routing, Dynamic Routing, and Hybrid Routing.
    • Dynamic Routing is used if multiple paths to the destination are available, and there are four Dynamic Routing Protocols: Distance Vector Protocols, Link-State Protocols, RIPv1, and OSPF.
    • OSPF is a link-state routing protocol that uses a link header protocol ID number 89 and has five packet types: Hello, Database Description, Link State Request, Link State Update, and Link State Acknowledgement.
    • OSPF Neighbor States are Down, Init, Two-way, Exstart, Exchange, Loading, and Full.
    • Every router has a unique ID in the routing domain expressed as an IP address, called the Router ID, and can be manually configured or chosen based on the highest IP of loopback or physical interfaces.
    • Loopback Interface is a virtual interface that provides stability to the Router ID where it is virtual and cannot fail.
    • The Router ID is essential in selecting the best path to the destination network using a single protocol metric, such as the number of hops in the RIP protocol.
