The last byte is the selector byte, which is 00
The six bytes prior make up the system ID
Everything before that is the area.
In this case, all three of your routers are in area 49.0001.
You can also verify the area with the output of 'show clns route'
*** Sample Output ***
R1#show clns route
Codes: C - connected, S - static, d - DecnetIV
I - ISO-IGRP, i - IS-IS, e - ES-IS
B - BGP, b - eBGP-neighbor
C 47.0001.1111.1111.1111.00 [1/0], Local IS-IS NET
C 47.0001 [2/0], Local IS-IS Area

Importance: Low
NET address of R2:
router isis
net 49.0001.0001.0001.0002.00
R6:
router isis
net 49.0001.0001.0001.0006.00
R3:
router isis
net 49.0001.0001.0001.0003.00
( I think the network address on R3 should be 49.0035.0001.0001.0003.00)
