[SR-Users] SCTP support for CDP

[Sergey Zyrianov]

Hi Carsten,

I did socat relay from TCP to SCTP and Diameter caps exchange seems to
happen. But CDP module still refuses to use this connection/peer:

 AAASendMessage(): AAASendMessage(): Can't find a suitable connected peer
in the routing table.
 0(1) ERROR: cdp [routing.c:275]: get_routing_peer(): get_routing_peer():
No connected DefaultRoute peer found for app_id 16777216 and vendor id
10415.


I suspect something wrong in the xml config for CDP I got - can I point
default route to TCP->SCTP relay? :
<DiameterPeer
....
        <Peer FQDN="10.47.10.153" Realm="ims.mncXX.mccYYY.3gppnetwork.org
<http://ims.mncxx.mccyyy.3gppnetwork.org/>" port="7868"/>
        <DefaultRoute FQDN="10.47.10.153" metric="10"/>
</DiameterPeer>

And this is HSS's response(ocr'ed from wireshark screenshot):

AVP: Result—Code(268) 1:12 f=—M— va1=DIAMETER_SUCCESS (2001)
