Hi,

 I have doubt regarding the setting of ATT bit when multiple areas are
involved. Consider the below situation,

      +----------------------------- R1 -------------------------+ 

       |                                               |
|

       |                                               |
|  

       |                                               |
|  

       |                                               |
|   

     R2 --------------------------- R4 ------------------------ R3

R2 is an L1 router, all others are L1L2 routers.

All routers belong to 2 areas 49 & 50.

Should R1 and R4 set the ATT bit in their L1 LSPs.???

It would be really helpful if anyone can explain this scenario.

Thanks,

Hemanth.
