Well, that would be a whole different issue within a single process. By
having multiple processes, you are using multiple databases (RIBs) within
the single router. So while you may have all the necessary routes yourself,
neighbors of one process will not know about routes from the other process
without redistribution.
Whether or not you care depends entirely on your architecture and lab!

Subject: Re: ISIS mutiple area question..
Hi. In regards to your statement "If you do multiple router isis portions,
they will need to redistribute into one another if you want to share
anything."
did you mean that one would have to redistribute from the level-2 process
into the
level-1 processes using redistribute isis ip level-2 into level-1
distribute-list 100
under each process?
Or is there another method?
router isis 12
net 12.0018.0018.0002.00
is-type level-2-only
!
router isis 22
net 49.0018.0018.0002.00
redistribute isis ip level-2 into level-1 distribute-list 100 is-type
level-1 !
router isis 26
net 50.0018.0018.0002.00
redistribute isis ip level-2 into level-1 distribute-list 101 is-type
level-1
Thanks,
Gerry
