Re: Opaque LSA Timers...

Your reasons for not supporting such variations
are agreeable but:
"If Ospf is providing a service to application (by
mean of Opaque LSA), there is every reason for
an application to except some priority service
in case of requirements."
Because flooding of application specific information
shouldn't be entirely retricted by base protocol
Possibly there is scope to explore ways to handle
such requirments in a generalized way.
