Thanks,

1) An application server is uniquely identified by a Routing Key. Now this
Routing key can be any combination of DPC/OPC/SI/CIC. This combination has
to be unique across the Application servers added.

What this means is that you can have two Application servers added such that
one AS has a Routing key type as DPC only with DPC=X and another having
Routing key type as DPC+OPC where DPC=X and OPC=Y.

2) In IPSP-IPSP scenario, the communication is between two M3UA endpoints
and the traffic has not be carried over the remote end as in the case of
ASP-SGP scenario where the traffic is originating from SS7 side and has to
be carried over to ASP OR is originating from ASP side and may be is
destined for some point code in SS7 cloud.

So point-to-point means that between two end-points in IP
domain/conceptually no services of SG being used..For ex, an MSC could be
talking to an SG and IP resident HLR at the same time. So in this case ,
MSC-HLR communication is IPSP-IPSP( point-to-point) and MSC-SG is ASP-SG.

As far as Routing Key type is concerned, it does not necessarily be
DPC-OPC.can be DPC only also.
[TOLGA]Just to prevent a confusion, IPSP-SE mandates DPC+OPC as RK, because
it relies on the assumption that RK will identify traffic at both ends.
IPSP-DE won't require that but it is also questionable whether it is a true
peer-to-peer model or two coupled client/server relationships. Actually for
IPSP-DE you will need to define to RKs, one for each direction of the
relationship, which combined would correspond to the single RK of IPSP-SE.

  [ANJALI]But Single/Double exchange only determines whether one/two UP,ACTIVE messages are required for both ends to be Up and Active and start receiving messages, why limitation on RK type?
