Guys,
The actual traffic will not be routed up to area 0... Area 0 has been
extended
down to R2, so R2 is now a backbone router. R2 has interfaces in 3 areas
now:
Area1, Area2, and Area0 by means of it's virtual link.
Any traffic originating in Area2 destined for Area1 will be routed directly
by
R2. This satisfies the "Interarea traffic must traverse the backbone" rule,
because R2 *is* a backbone router.
This is not theory... It is fact.
Alan
