The system may advertise, on the client-side, SCTP alternate addresses that are in a route-domain different from that of the virtual server.


No impact to traffic processing. Some addresses advertised may fail to respond to negotiation, but the SCTP association overall will be stable.


Configuring an SCTP virtual server with alternate-addresses that are not in the correct route domain.


Ensure that all addresses for SCTP virtual servers are in the same route domain.

Fix Information

The SCTP profile now screens alternate addresses for route domain membership before advertising them.
