NAME

     ip6addrctl -- configure address selection policy for IPv6 and IPv4

SYNOPSIS

     ip6addrctl [show]
     ip6addrctl add prefix precedence label
     ip6addrctl delete prefix
     ip6addrctl flush
     ip6addrctl install configfile

DESCRIPTION

     The ip6addrctl utility manages the policy table of source and destination address selection for outgoing IPv4 and IPv6 packets.  When
     ip6addrctl is invoked without an argument or with a single argument show, it prints the content of the policy table currently installed in
     the kernel.

     To modify the table, the following operations are available:

     add prefix precedence label
	     Add a policy entry.  The prefix argument is an IPv6 prefix, which is a key for the entry.	An IPv4 prefix should be specified with an
	     IPv6 prefix using an IPv4-mapped IPv6 address.  The precedence and label arguments are decimal numbers, which specify the precedence
	     and label values for the entry, respectively.  This operation should be performed without an existing entry for the prefix.

     delete prefix
	     Delete a policy entry specified by prefix, which should be an IPv6 prefix.  A corresponding entry for the prefix should have already
	     been installed.

     flush   Delete all existing policy entries in the kernel.

     install configfile
	     Install policy entries from a configuration file named configfile.  The configuration file should contain a set of policy entries.
	     Each entry is specified in a single line which contains an IPv6 prefix, a decimal precedence value, and a decimal label value, sepa-
	     rated with white space or tab characters.	In the configuration file, lines beginning with the pound-sign ('#') are comments and are
	     ignored.

EXIT STATUS

     The ip6addrctl utility exits 0 on success, and >0 if an error occurs.

HISTORY

     The ip6addrctl utility first appeared in the KAME IPv6 protocol stack kit.  The original command name was addrselect, but it was then renamed
     to the current one so that the name would describe its function well.
