Thanks for all responses.
I think the optin with net x.x.x.x 0.0.0.0 is the right one. I do not
think that ACL is the soltion.

Also this problem rise another one.
What is the best way to announce net in a protocol?
Just to put the interface in the protocol with same command (where the
protocol permit) or to announce the entire network?
What do you think about the grading in the real exam? I will get the
points if i announce the /32 net. (of course if the task does not
restrict me in any way, just says put this net/interface in the protocol
domain)

Thanks
