Brian,
I think in some scenarios, mixing SE and DE becomes more practical.
Please look at following scenario:
----------
------------
|IPSP
1|----------------------|IPSP A |
----------
-----------
1) IPSP1 is serving AS-1(PC 111) and IPSP A is serving AS-A(PC 999) with
rc=x. They are running happily in single exchange mode.
2) Now, I want to add an additional AS at IPSP1 ex: AS2(PC 222). For AS2, I
need to configure a new RC(rc=y).
3) Corresponding to rc=y, I need to send ASP-Active towards IPSP-A. Since
there is no local AS with rc=y at IPSP-A, it would return with error code
"invalid RC", unless there is some way to instruct IPSP-A to behave as a
double-exchange IPSP for rc=y. Although I could do the workaround by adding
a dummy AS with rc=y at IPSP-A but that solution is irrational and not so
clean.
Regards,
Ankit
