Final answer:
The type of routing protocol that sends the entire routing table to its neighbors is the distance vector routing protocol.
Step-by-step explanation:
The type of routing protocol that sends the entire routing table to its neighbors is known as a distance vector routing protocol. This protocol relies on routers sending the entire routing table to their immediate neighbors at a regular interval. Each router then combines the received routing table with its own to update its routing information. This method can potentially lead to routing loops but has mechanisms like split horizon, route poisoning, and hold-down timers to prevent them. Contrastingly, link-state routing protocols send only information about the direct links of a router to all the nodes in the network, enabling a more up-to-date and reliable routing decision process.
