Why with "SCTP" connections using IPv6 addresses, the connection continues to use the primary address for heartbeat/heartbeat_ack exchange over secondary path when the primary path is down in RHEL?
Issue
- With this multi-homed interfaces, if primary path was interrupted, secondary addresses were not chosen to forward the SCTP
Heartbeat/Heartbeat_ACKand this resulted with theSCTPdisruption. - After primary addresses were deleted,
SCTPHeartbeat/Heartbeat_ACK was forwarded using the deleted primaryIPv6addresses using secondaryIPv6MAC address.
Environment
- Red Hat Enterprise Linux (RHEL) 7.
- Red Hat Enterprise Linux (RHEL) 6.
