Hi Folks,

In the figure below, LSR's R1, R2 and R3 are in the same bridging
domain (i.e. they have atleast one interface in a common subnet ).
The common subnet is say S. Note that the physical connectivity
is thru ATM.

            R1 --------------  R2 ------------ R3

In the Hello exchange should R1 and R3 see each other as peers.
If yes then what is the significance of the ATM Label Range
( indicated in the Initialization message) between R1 and R3,
since they are connected thru R2 physically ?

Regards
