On-link NDP IPv6

Hello.

I am completely new in IPv6 and I started reading RFC 4861 for NDP.

Can anyone help me understand the purpose of on-link prefixes and off-link prefixes? I believe the routers can advertise networks (using RA) as on-link or off-link. Does this mean that if I have two different prefixes on the same link (lets say 2001::/64 and 2002::/64) and two host (each one on a different prefix and seeing the other prefix as on-link) they can communicate with each other without the help of a router?

Also, I don´t see a pratical use for this (on-link and off-link). Anyone can help with an example?

Any help would be highly appreciated.

Regards,

Joao

P.S. - hope the questions don´t look silly
