What happens if a RIP update packet is lost?

Hello,

i am currently learning for an exam. One topic is the routing protocol RIP.

This is my question:

Suppose a RIP router wants to advertise 30 routes. Two datagrams are required for transmission: one datagram with 25 routes and a second datagram with the remaining 5 routes. Assume that the first datagram does not reach its destination. What happens?

​

Well my understanding is that the network is wrong advertised to the next router until the next periodic update comes in after 30 seconds. So that means the network is inconsistent for a short time. Is that correct or am i missing something?
