You are right. That is a missing part. We need to have a solution for "IP prefix exchanges in V2V and V2I” The need of IP prefix exchanges is clear and well presented in PS documents for IP in V2V and V2I. Then, there are 2 documents already existing as below:

1. https://tools.ietf.org/html/draft-petrescu-autoconf-ra-based-routing-00
2. https://tools.ietf.org/html/draft-jhlee-mext-mnpp-00

The above 2 documents are the early effort to establish IP direction communications between vehicles and also between a vehicle and a road side unit. 

I officially request that we should have a solution for IP prefix exchanges as a work item.

Cheers!
