I try to connect 2 STPs to each other via Sigtran M3UA protocol.

But I don't understand, why my connection is fault. Could you please check my configuration?

  STP1                              STP2
  point-code 0.12.4           point-code 0.12.4
  port 2905                        port 2906
  IP 172.18.141.1              IP 172.18.142.2

Me configuration is:

STP1 

cs7 instance 1

 network-indicator reserved
 point-code 0.12.4
 asp stp2 2906 2905 m3ua
  local-ip 172.18.141.1
  remote-ip 172.18.142.2
  role asp
  sctp-role client
 as stp2 m3ua
  asp stp2
  traffic-mode override
  routing-key 0 0.25.0
 route-table system
 

STP2

cs7 instance 1
 network-indicator reserved
 point-code 0.25.0
 asp stp1 2905 2906 m3ua
  local-ip 172.18.142.2
  remote-ip 172.18.141.1
  role sg
 as stp1 m3ua
  asp stp1
  traffic-mode override
  routing-key 0 0.12.4
 route-table system
 listen m3ua 2906

Thanks in advance!
