the trick in my question was that i was expecting the command to look like
redistribute isis (tag) ip level-2 into level-1 distrbuite-list 100
however the ( tag ) is not required , probably because you can run only one
level 2 process on the router .
to comment on your answer , L1 router can accept redistribution from level2
(typically this redistibution will be on L1/2 router ) .
to run multi-area on single interface , you have to put multiple NET commands
under the same process , this scenarios is used for migration purposes

FYI-L1 is NSSA (eq OSPF) by default
ie it allows redistribtion, if it was totally stubby it wont allow
redistribution
L1 only intraarea
L2 can be Inter Area or Intra Area
L1/L20 is like ABR in OSPF
i have one question. How can you have multiple interface be part of
different ISIS area's . But with single ISIS process.
*Say R1 *
Eth 0/0 to be part of 49.4004 and Eth 0/1 be part of 49.4008. But only one
process allowed is on the router 'router isis 10'
And how will you differentiate which interface is part of which area?
