just trying to make sense of some things i've noticed with isis
i know that level-1 areas act like stub areas, and level-2 areas act like
transit areas.
question 1: should you be able to ping from a level 2 area to a level 1
router, if that router is NOT directly connected? e.g.- not a level-1-2
router.
question 2: if you have a router that belongs to 2 areas, does that mean that
the router must be a level-1-2 or at least a level-2? i seem to remember an
IE lab where there was a router <R6> that had a level-1 adjaceny to BB1 and a
level-1-2 adjaceny to another router. is it possible for a router to have 2
level-1 adjacenies to two different networks (and still pas on routing updates
between them)? this lab i'm talking about had:
BB1-----level-1 areaY--------R6--------level-2--areaZ-----------R3----
and it was able to pass the routes from bb1 to r3 <if i remember at all
correctly>
just trying to get my facts straight.
