I wonder how it works with a point-to-point after changing it back from
point-to-m. Does this configuration survive a "clear ip ospf process"?
can you post the config of the 3 routers (interfaces, router ospf)?
Point-to-point is capable of being adjacent with a single neighbor, hence
Virtual-template on R5 (the hub) should change otherwise it can't form
adjacency with the 2 spokes.
