Hi Sina,

Is such a conf possible application of TA ?

    R1---- bkbone ----R2---- area 2 ------R7
     |                |                    |
     |                |                    |
   area1            area1                  |
     |                |                    |
     |                |                  area 2
    R3---- area1 -----R4                   |
     |                                     |
     |                                     |
    area2                                  |
     |                                     |
     |                                     |
    R6-------------------------------------

Now link between R6 and R7 in area 2 is broken.
Could a TA can be configured between :
1)R3 and R2 (through area 1 and bkbone ie R3 - R1 and R2)
   beloging to area 2 for repair of area 2.
2)R3 and R2 (through area 1 ie R3-R4 and R2)
   belogning to area 2 .
To repair the area partition.

In short could TTA (ie transit area) span
through multiple areas ?

Further could TA belong to an area ie TTA to
whom none of the ABRS (between which TA is
configured attached).

thanks,
vivek
