If a tmm connflow gets an ICMP unreachable message, the system typically terminates the connflow. However, if the connflow gets an ICMP unreachable from another virtual server through VIP2VIP, the connflow remains alive.
connflow remains until timeout. Although the active connection costs some resources, the impact is minor.
This occurs in VIP2VIP configurations.
None
if the connflow gets an ICMP unreachable from another virtual server through VIP2VIP, the connflow is now terminated, which is correct behavior.
