What is the purpose of flooding in distributing link state packets?
What is the purpose of flooding in distributing link state packets?
- To prevent loops and inconsistencies in routing tables
- To send packets in a controlled manner
- To prioritize packet delivery based on router ID
- To distribute packets to all routers without regard for bandwidth (correct)
In which scenario should the link state packets be built according to the text?
In which scenario should the link state packets be built according to the text?
- When a router's age in the network increases significantly
- When a line cost in the network decreases slightly
- When a subnet is added to the network
- When a neighbor router changes its properties appreciably (correct)
What is the main challenge with routers using different versions of the topology?
What is the main challenge with routers using different versions of the topology?
- Improved network stability but slower data transmission
- Potential for inconsistencies, loops, and unreachable machines (correct)
- Higher speed but more inconsistencies
- Increased bandwidth consumption
