The remote router is the only router in area 66. (in addition to ABR and
this the only ospf connection that remote router has)
I cannot configure it on in side since it does not have the software version
that supports this.
But is not this supposed to work this way too ? According to the
documentation I do not see any reason to not be working in out direction
except maybe that both router involved must support this features.
