People, am I being stupid? I will take a look at that lab on Tuesday. I
clearly remember that they explicitly said not to use "ip ospf network"
statement.

Yes, you guys are right that we weren't allowed to use "frame map"
statements on the spokes. And it's ok. That was not the point of the lab.
The point was that we couldn't use "ip ospf network multipoint" statement,
which would fix the entire scenario by creating /32 routes on the spokes
pointing to the hub. So since we couldn't do it, we had to create policy
routing that would send traffic to the hub manually.

Am I right?
