DHCPv6 server
-------------
VyOS provides DHCPv6 server functionality which is described in this section.
In order to use the DHCPv6 server it has to be enabled first:
.. code-block:: none
set service dhcpv6-server
To restart the DHCPv6 server (operational mode):
.. code-block:: none
restart dhcpv6 server
To show the current status of the DHCPv6 server use:
.. code-block:: none
show dhcpv6 server status
Show statuses of all assigned leases:
.. code-block:: none
show dhcpv6 server leases
DHCPv6 server options
^^^^^^^^^^^^^^^^^^^^^
DHCPv6 server preference value
******************************
Clients receiving advertise messages from multiple servers choose the server
with the highest preference value. The range for this value is `0...255`. Set
a preference value for the DHCPv6 server:
.. code-block:: none
set service dhcpv6-server preference <preference value>
Delete a preference:
.. code-block:: none
set service dhcpv6-server preference
Show current preference:
.. code-block:: none
show service dhcpv6-server preference
Specify address lease time
**************************
The default lease time for DHCPv6 leases is 24 hours. This can be changed by
supplying a `default-time`, `maximum-time` and `minimum-time` (all values in
seconds):
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> lease-time {default <default-time> | maximum <maximum-time> | minimum <minimum-time>}
Reset the custom lease times:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> lease-time {default | maximum | minimum}
Show the current configuration:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> lease-time {default | maximum | minimum}
Specify NIS domain
******************
A Network Information (NIS) domain can be set to be used for DHCPv6 clients:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> nis-domain <nis-domain-name>
To Delete the NIS domain:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> nis-domain <nis-domain-name>
Show a configured NIS domain:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> nis-domain <nis-domain-name>
Specify NIS+ domain
*******************
The procedure to specify a Network Information Service Plus (NIS+) domain is
similar to the NIS domain one:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> nisplus-domain <nisplus-domain-name>
To Delete the NIS+ domain:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> nisplus-domain <nisplus-domain-name>
Show a configured NIS domain:
# show service dhcpv6-server shared-network-name <name> subnet <ipv6net> nisplus-domain <nisplus-domain-name>
Specify NIS server address
**************************
To specify a NIS server address for DHCPv6 clients:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> nis-server <IPv6 address>
Delete a specified NIS server address:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> nis-server <IPv6 address>
Show specified NIS server addresses:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> nis-server
Specify NIS+ server address
***************************
To specify a NIS+ server address for DHCPv6 clients:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> nisplus-server <IPv6 address>
Delete a specified NIS+ server address:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> nisplus-server <IPv6 address>
Show specified NIS+ server addresses:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> nisplus-server
Specify a SIP server address for DHCPv6 clients
***********************************************
By IPv6 address
###############
A Session Initiation Protocol (SIP) server address can be specified
for DHCPv6 clients:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> sip-server-address <IPv6 address>
Delete a specified SIP server address:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> sip-server-address <IPv6 address>
Show specified SIP server addresses:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> sip-server-address
By FQDN
#######
A name for SIP server can be specified:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> sip-server-name <sip-server-name>
Delete a specified SIP server name:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> sip-server-name <sip-server-name>
Show specified SIP server names:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> sip-server-name
Simple Network Time Protocol (SNTP) server address for DHCPv6 clients
*********************************************************************
A SNTP server address can be specified for DHCPv6 clients:
.. code-block:: none
set service dhcpv6-server shared-network-name <name> subnet <ipv6net> sntp-server-address <IPv6 address>
Delete a specified SNTP server address:
.. code-block:: none
delete service dhcpv6-server shared-network-name <name> subnet <ipv6net> sntp-server-address <IPv6 address>
Show specified SNTP server addresses:
.. code-block:: none
show service dhcpv6-server shared-network-name <name> subnet <ipv6net> sntp-server-address
DHCPv6 address pools
^^^^^^^^^^^^^^^^^^^^
DHCPv6 address pools must be configured for the system to act as a DHCPv6
server. The following example describes a common scenario.
Example 1: DHCPv6 address pool
******************************
A shared network named `NET1` serves subnet `2001:db8:100::/64` which is
connected to `eth1`, a DNS server at `2001:db8:111::111` is used for name
services. The range of the address pool shall be `::100` through `::199`. The
lease time will be left at the default value which is 24 hours.
.. code-block:: none
set service dhcpv6-server shared-network-name NET1 subnet 2001:db8:100::/64 address-range start 2001:db8:100::100 stop 2001:db8:100::199
set service dhcpv6-server shared-network-name NET1 subnet 2001:db8:100::/64 name-server 2001:db8:111::111
Commit the changes and show the configuration:
.. code-block:: none
commit
show service dhcpv6-server
shared-network-name NET1 {
subnet 2001:db8:100::/64 {
address-range {
start 2001:db8:100::100 {
stop 2001:db8:100::199
}
}
name-server 2001:db8:111::111
}
}
Static mappings
^^^^^^^^^^^^^^^
In order to map specific IPv6 addresses to specific hosts static mappings can
be created. The following example explains the process.
Example 1: Static IPv6 MAC-based mapping
****************************************
IPv6 address `2001:db8:100::101` shall be statically mapped to a device with
MAC address `00:15:c5:b7:5e:23`, this host-specific mapping shall be named
`client1`.
.. note:: The MAC address identifier is defined by the last 4 byte of the
MAC address.
.. code-block:: none
set service dhcpv6-server shared-network-name NET1 subnet 2001:db8:100::/64 static-mapping client1 ipv6-address 2001:db8:100::101
set service dhcpv6-server shared-network-name NET1 subnet 2001:db8:100::/64 static-mapping client1 identifier c5b75e23
Commit the changes and show the configuration:
.. code-block:: none
show service dhcp-server shared-network-name NET1
shared-network-name NET1 {
subnet 2001:db8:100::/64 {
name-server 2001:db8:111::111
address-range {
start 2001:db8:100::100 {
stop 2001:db8:100::199 {
}
}
static-mapping client1 {
ipv6-address 2001:db8:100::101
identifier c5b75e23
}
}
}
