24 Questions
What is IP Routing?
IP Routing is the process of forwarding a packet from its source to its destination through a routed network.
What is the purpose of a Routing Protocol?
Routing Protocol is used to transfer information learned by each router to other routers to build the routing table.
What is OSPF?
OSPF is a Routing Protocol that selects the best path to transfer information between routers.
What is Routed Protocol?
Routed Protocol refers to IP packets that are routed between the routers, such as IPv4 and IPv6.
What is Autonomous System?
Autonomous System is a collection of devices under the same administrative authority.
What are the three types of Routing Protocol?
The three types of Routing Protocol are Static Routing, Dynamic Routing, and Hybrid Routing.
What are the OSPF Neighbor States?
The OSPF Neighbor States are Down, Init, Two-way, Exstart, Exchange, Loading, and Full.
Question 1
What is the purpose of electing a Designated Router (DR) and a Backup Designated Router (BDR) in OSPF multi-access networks?
Answer 1
To prevent the possibility of many neighbor relationships on the same physical segment.
Question 2
What are the two conditions for establishing adjacency between two OSPF routers?
Answer 2
Hello interval and Dead interval must be equal, and any two interfaces must have the same network type.
Question 3
What are the advantages of using OSPF areas?
Answer 3
Smaller database about the link state and the ability to isolate the unstable area.
Question 4
What is the formula to calculate the cost metric in OSPF?
Answer 4
Cost = Reference Bandwidth / Interface Bandwidth.
Question 5
What is the purpose of the OSPF backbone area (Area 0)?
Answer 5
All other areas must have a connection into Area 0.

- 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.
