Opened: Jul 24, 2018 Severity: 3-Major
When multihoming is enabled in an SCTP profile, the source-address of the INIT chunk was not added as an Address parameter in that INIT chunk.
No impact for peers that implement SCTP in accordance with RFC 4960. RFC does not require that the address either should or should not be included in the INIT chunk, but does require that an entity receiving an INIT chunk include the source-address in its list regardless of whether that is included in the INIT chunk.
Any SCTP profile where multi-homing is enabled.
No known workaround.
BIG-IP now includes all relevant addresses in the INIT chunk.
When multihoming is enabled, the local address will now be added to the INIT chunk. Previously the local address (that is, the address that the datagram is sent from) was not listed as an Address parameter. This is permitted, but not required, by RFC 4960 section 3.3.2.1.
