Need help to setup RIP correctly

Hi there im trying to setup rip at the moment.
i have followed the steps on http://wiki.mikrotik.com/wiki/How_to_set_wireless_client_and_Ethernet

But what i want to know is must rip also be setup on the AP?

And do i still need to add masquerade to the router? I have followed the step but does not work. What i want to do is to allow everyone in my town to connect to each other and share data

Any help would help alot
