Error description
After putting an IP alias, then deleting the original address and putting it again, different source IP address is chosen depending on the order of parameter when it was deleted. The problem happens only when ifconfig is called by the order "ifconfig [interface] [address] delete". For example: Given an interface enX has IP address A.A.A.A. Goodcase: # ifconfig enX alias B.B.B.B netmask 255.255.255.0 # ifconfig enX delete A.A.A.A # ifconfig enX alias A.A.A.A netmask 255.255.255.0 # traceroute C.C.C.C -> B.B.B.B is used as source address Badcase: # ifconfig enX alias B.B.B.B netmask 255.255.255.0 # ifconfig enX A.A.A.A delete # ifconfig enX alias A.A.A.A netmask 255.255.255.0 # traceroute C.C.C.C -> A.A.A.A is used as source address
Local fix
Use ifconfig [interface] "delete [address]" syntax instead of "[address] delete".
Problem summary
After deleting the ip_address using syntax "ifconfig interface ip_address delete", the routing table will continue to display the deleted ip_address as route.
Problem conclusion
For the syntax "ifconfig interface ip_address delete", the internal flags set properly & ipaddress is deleted.
Temporary fix
