Sigtran configuration : Connection to multi-homed STP as client?

[Hussien AlMaain]

Dears,


Could you please help me with configuration for the following diagram.

Note:
STP 1 and 2 for SCCP provider.
STP 3 Restcomm SMSC .


Thanks in advance.

If I have the following information:
STP1
    <IP1> <Port1>
    <IP2> <Port1>
    <ISPC1>
    <remote ssn 1>

STP2
    <IP3> <Port2>
    <IP4> <Port2>
    <ISPC2>
    <remote ssn 2>

STP3
    <IP10> <Port10>
    <IP11> <Port11>
    <SPC3>
    <GT1>

Does this command create needed connections?

sctp association create stp1 CLIENT <IP1> <Port1> <IP10> <Port10>
    # note: can we configure the peer host like this: sctp association create stp1 CLIENT <IP1>,<IP2> <Port1> <IP10> <Port10>
    # or I should to configure sepreated association for <IP2> like this: sctp association create stp2 CLIENT <IP2> <Port1> <IP10> <Port10>
   
sctp association create stp3 CLIENT <IP3> <Port2> <IP11> <Port11>
    # note: can I configure the peer host like this: sctp association create stp3 CLIENT <IP3>,<IP4> <Port2> <IP11> <Port11>
    # or I should to configure sepreated association for <IP4> like this: sctp association create stp4 CLIENT <IP4> <Port2> <IP11> <Port11>
 
 
to continue m3ua and sccp configuration I should complete the sctp first, so please advice.

Note:
<ISPC1> and <ISPC1> are International Signaling Point Code of SCCP carrier
<SPC3> is Signaling Point Code of RestComm SMSC gateway

I will try to configure both cases, so please correct me.

In case 1:
<IP1> and <IP2> in sctp1 as peer address's
<IP3> and <IP4> in sctp2 as peer address's
----------------------------------------------------

case 2:

sctp association create stp1 CLIENT <IP1> <Port1> <IP10> <Port10>

sctp association create stp2 CLIENT <IP2> <Port1> <IP10> <Port10>
   
sctp association create stp3 CLIENT <IP3> <Port2> <IP11> <Port11>

m3ua as add AS1 ASP2

 I read about SCTP Dynamic Address Reconfiguration "ASCONF", so does it mean that, I shouldn't care about <IP2> and <IP4> in SCTP configuration, because it's just for redundancy in Standalone STP1 and STP2, please advice!!!   

[Hussien AlMaain]

So, the configuration will be like this:

sctp association create stp1 CLIENT <IP1> <Port1> <IP10> <Port10>   

sctp association create stp2 CLIENT <IP3> <Port2> <IP10> <Port10>

m3ua asp create ASP1 stp1
m3ua asp create ASP2 stp2

m3ua as create AS1 IPSP mode DE ipspType CLIENT
m3ua as create AS2 IPSP mode DE ipspType CLIENT

m3ua as add AS1 ASP1

m3ua as add AS2 ASP2
