  • Closed as program error.

Error description

  • When an alias IP is added to an interface with firstalias
    keyword, routing entry is updated with the newly added
    alias IP address if it is in the same subnet as the
    existing
    IP address of the interface. When the 2nd alias IP of the
    same subnet is added, netstat -rn does not give the
    updated
    route entry with the new IP address as its gateway.
    
    But, outgoing packets use the correct source IP address.
    

Local fix

Problem summary

  • netstat -rn is showing wrong route entry after
    adding the 2nd alias IP with firstalias keyword.
    

Problem conclusion

  • Extra condition is added to check if newly added gateway is
    different from the existing one. If it is different, then make
    the newly added IP as the gateway.
    

Temporary fix
