Vincent Nogues,
This email is intended to be vender neutral discussions
wrt OSPF. IMO, if the more dynamic links are separated
and associated with one or more separate areas, then
convergence time should improve and the amount of CPU
resources should decrease.
I do not have a rule of thumb on the number of routers
in an area, but without BMA type links, this number seems
excessive for a single area.
