OSPF / ISIS Redist.

Ok what does the following mean:
 
router isis
 redistribute ospf 1 metric 32 metric-type internal level-1-2
 
I take it to mean:
Redistribute OSPF Process 1 into ISIS with a metric of 32.
Make those routes ISIS internal
 
But what does that level-1-2 mean? OSPF does not have level-1-2 routes.
 
Also, under the OSPF process the solution is listed as:
 
router ospf 1
redistribute isis level-1-2 metric 100 metric-type 1 subnets tag 1024
 
I take this to mean:
Redistribute ISIS process (both level 1,2 routes)
Make them External Type1, classless
 
Now what is the tag for? I know that when I do a 'sh ip ospf data' it
marks these routes with that tag, but what significance does the tag
play with any route process?
 
It seems that redistribution is a weak point of mine, so I am trying to
get this down!
