The output of `route -A inet6` does not display properly when the 'Use' column output is over 6 digits

Solution In Progress - Updated -

Issue

  • The old route command's output for IPv6 does not always include a space between the values in the Ref and Use columns:

    [root@r75 ~]# route -n -A inet6
