I have been reading the BRSKI I-D. While the I-D is pretty clear as to
what happens when everything goes as planned, I am finding it very
difficult to understand what will happen when a Pledge contacts a
Registrar for a different domain.
Consider the following scenario:
Domain A Domain B
.............................. ...............................
. --------- . . --------- .
. | Reg A | . . | Reg B | .
. --------- . . --------- .
. . . .
. . . .
. ----------- . . ----------- .
. | Proxy A | . . | Proxy B | .
. ----------- . . ----------- .
.............................. ...............................
----------
| Pledge |
----------
A Pledge is at the edge of Domain A (which it should join) and has
discovered Proxy A. It is also at the edge of Domain B, and has
discovered Proxy B. It then begins the steps outlined in Figure 2, and
by chance chooses to contact the Registrar offered by Proxy B.
While I understand that this attempt to register will fail, it is not
clear at what point the Pledge will realize that this is the wrong
Registrar, and move on to the next discovered Proxy. Clearly the Proxy
does not know; it is only a conduit. Does the Registrar have enough
information, or is it only after the voucher is issued (or not issued)
by the MASA that the decision can be made?
Would someone please help me to clarify this issue?
Bill
