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, separated with
white space or tab characters.
In the configuration file, lines beginning with the pound-sign
(‘#’)
are
comments and are ignored.
