Which two of the following are true regarding the distance-vector and ...
Understanding Routing Protocols
Routing protocols are essential for efficient data transfer across networks. Two primary categories of routing protocols are distance-vector and link-state protocols.
Key Differences
- Distance Vector Protocols:
- These protocols send their entire routing table to all adjacent neighbors at regular intervals.
- They do not send updates based on the state of their own links but rather share the routes they know about.
- Link State Protocols:
- Link-state protocols, on the other hand, disseminate information about the state of their own links to all routers in the network.
- This information is sent as updates, allowing each router to construct a complete view of the network topology.
Evaluating the Statements
1. Link state sends its complete routing table out all active interfaces on periodic time intervals.
- This statement is false. Link-state protocols do not send their entire routing table periodically; they send updates only when there are changes in the network.
2. Distance vector sends its complete routing table out all active interfaces on periodic time intervals.
- This statement is true. Distance-vector protocols share their complete routing information at regular intervals.
3. Link state sends updates containing the state of its own links to all routers in the internetwork.
- This statement is true. Link-state protocols send specific updates about their own links, thus allowing all routers to have an accurate picture of the network.
4. Distance vector sends updates containing the state of its own links to all routers in the internetwork.
- This statement is false. Distance-vector protocols do not share the state of their links; they only share their routing tables.
Conclusion
Thus, the correct answer is option 'C', which states that statements 2 and 3 are true regarding the distance-vector and link-state routing protocols.
