For the providers that run it to the edge the comments from students that I
have had that actually do it they say area 0 is always extended to the
provider. They had never allowed a customer to connect with anything except
Area 0.

Subject: OSPF Sham links in real life
In my workbooks sham-links are presented as a way of tricking the router to
send traffic via MPLS cloud and not via the backup link, when OSPF is
redistributed via MBGP.
My question is:
On real networks, is it practical to configure sham links even if no backup
links are installed? The reason for this would be to avoid confusion with O
and IA routes, so routes originated in the same area are seen as internal
routes O and not inter-area IA.
thx
