DHCPv6 Server
Junos OS device can act as a DHCPv6 server and allocates IP addresses to IPv6 clients. DHCPv6 server also delivers configuration settings to client hosts on a subnet or to the requesting devices that need an IPv6 prefix. The DHCPv6 local server sends and receives packets using the IPv6 protocol and informs IPv6 of the routing requirements of router clients. For more information, read this topic.
DHCPv6 Local Server Overview
The DHCPv6 local server is compatible with the DHCP local server and the DHCP relay agent, and can be enabled on the same interface as either the extended DHCP local server or DHCP relay agent.
The DHCPv6 local server provides many of the same features as the DHCP local server, including:
Configuration for a specific interface or for a group of interfaces
Site-specific usernames and passwords
Numbered Ethernet interfaces
Statically configured CoS and filters
AAA directed login
Use of the IA_NA option to assign a specific address to a client
When a DHCPv6 client logs in, the DHCPv6 local server can optionally use the AAA service framework to interact with the RADIUS server. The RADIUS server, which is configured independently of DHCP, authenticates the client and supplies the IPv6 prefix and client configuration parameters.
The client username, which uniquely identifies a subscriber or a DHCP client, must be present in the configuration in order for DHCPv6 local server to use RADIUS authentication.
You can configure DHCPv6 local server to communicate the following attributes to the AAA service framework and RADIUS at login time:
Client username
Client password
Based on the attributes that the DHCPv6 local server provides, RADIUS returns the information listed in Table 1 to configure the client:
Table 1: RADIUS Attributes and VSAs for DHCPv6 Local Server
Attribute Number | Attribute Name | Description |
|---|---|---|
27 | Session-Timeout | Lease time, in seconds. If not supplied, the lease does not expire |
123 | Delegated-IPv6-Prefix | Prefix that is delegated to the client |
26-143 | Max-Clients-Per-Interface | Maximum number of clients allowed per interface |
To configure the extended DHCPv6 local server on the router (or switch), you include the dhcpv6 statement at the [edit system services dhcp-local-server] hierarchy level.
You can also include the dhcpv6 statement at the following hierarchy levels:
[edit logical-systems logical-system-name system services dhcp-local-server]
[edit logical-systems logical-system-name routing-instances routing-instance-name system services dhcp-local-server]
[edit routing-instances routing-instance-name system services dhcp-local-server]
DHCPv6 Server Overview
A Dynamic Host Configuration Protocol version 6 (DHCPv6) server can automatically allocate IP addresses to IPv6 clients and deliver configuration settings to client hosts on a subnet or to the requesting devices that need an IPv6 prefix. A DHCPv6 server allows network administrators to manage pool of IP addresses centrally among hosts and to automate the assignment of IP addresses in a network.
SRX Series devices do not support DHCP client authentication. In a DHCPv6 deployment, security policies control access through the device for any DHCP client that has received an address and other attributes from the DHCPv6 server.
Some features include:
Configuration for a specific interface or a group of interfaces
Stateless address autoconfiguration (SLAAC)
Prefix delegation, including access-internal route installation
DHCPv6 server groups
The DHCPv6 server configuration usually consists of DHCPv6 options for clients, an IPv6 prefix, an address pool that contains IPv6 address ranges and options, and a security policy to allow DHCPv6 traffic. In a typical setup the provider Juniper Networks device is configured as an IPv6 prefix delegation server that assigns addresses to the customer edge device. The customer’s edge router then provides addresses to internal devices.
To configure DHCPv6 local server on a device, you include the DHCPv6 statement at the [edit system services dhcp-local-server] hierarchy level. You then create an address assignment pool for DHCPv6 that is configured in the [edit access address-assignment pool] hierarchy level using the family inet6 statement.
You can also include the dhcpv6 statement at the [edit routing-instances routing-instance-name system services dhcp-local-server] hierarchy.
Existing DHCPv4 configurations in the [edit system services dhcp] hierarchy are not affected when you upgrade to Junos OS Release 10.4 from an earlier version or enable DHCPv6 server.

Example: Configuring DHCPv6 Server Options
This example shows how to configure DHCPv6 server options on SRX1500, SRX5400, SRX5600, and SRX5800 devices.
Requirements
Before you begin:
Determine the IPv6 address pool range.
Determine the IPv6 prefix. See the Understanding Address Books.
Determine the grace period, maximum lease time, or any custom options that should be applied to clients.
List the IP addresses that are available for the devices on your network; for example, DNS and SIP servers.
Overview
In this example, you set a default client limit as 100 for all DHCPv6 groups. You then create a group called my-group that contains at least one interface. In this case, the interface is ge-0/0/3.0. You set a range of interfaces using the upto command and set a custom client limit as 200 for group my-group that overrides the default limit. Finally, you configure interface ge-0/0/3.0 with IPv6 address 2001:db8:3001::1/64 and set router advertisement for interface ge-0/0/3.0. Starting with Junos OS Release 15.X49-D70 and Junos OS Release 17.3R1, you can add the option dynamic-server to dynamically support prefix and attributes that are updated by the WAN server.
A DHCPv6 group must contain at least one interface.

Specifying the Address Pool for IPv6 Prefix Assignment
The DHCPv6 server configuration usually consists of DHCPv6 options for clients, an IPv6 prefix, an address pool that contains IPv6 address ranges and options, and a security policy to allow DHCPv6 traffic. In a typical setup, the provider Juniper Networks device is configured as an IPv6 prefix delegation server that assigns addresses to the customer edge device. The customer’s edge router then provides addresses to internal devices.
To configure DHCPv6 local server on a device, you include the DHCPv6 statement at the [edit system services dhcp-local-server] hierarchy level. You then create an address assignment pool for DHCPv6 that is configured in the [edit access address-assignment pool] hierarchy level using the family inet6 statement.
You can also include the dhcpv6 statement at the [edit routing-instances routing-instance-name system services dhcp-local-server] hierarchy.
Existing DHCPv4 configurations in the [edit system services dhcp] hierarchy are not affected when you upgrade to Junos OS Release 10.4 from an earlier version or enable DHCPv6 server.
To configure the address pool for DHCPv6 local server:
- Set address-assignment pool name, family name, and prefix.[edit access]user@host# set address-assignment pool POOL family inet6 prefix 2001:db8::/32
- Set range. [edit access]user@host# set address-assignment pool POOL family inet6 range RANGE1 low 2001:db8::2/32user@host# set address-assignment pool POOL family inet6 range RANGE1 high 2001:db8::aaaa/32
Specifying the Delegated Address Pool for IPv6 Prefix Assignment
You can explicitly specify a delegated address pool:
On routers—Subscriber management uses the pool to assign IPv6 prefixes for subscribers. You can specify the delegated address pool globally, for a specific group of interfaces, or for a particular interface.
On switches—DHCP management uses the pool to assign IPv6 prefixes for DHCP clients. You can specify the delegated address pool globally, for a specific group of interfaces, or for a particular interface.
You can also use by Juniper Networks VSA 26-161 to specify the delegated address pool. The VSA-specified value always takes precedence over the delegated-address statement.
To configure the delegated address pool for DHCPv6 local server:
- Specify that you want to configure override options. [edit system services dhcp-local-server dhcpv6]user@host# edit overrides
- Configure the delegated address pool.[edit system services dhcp-local-server dhcpv6 overrides]user@host# set delegated-pool paris-cable-12

Preventing Binding of Clients That Do Not Support Reconfigure Messages
The DHCPv6 client and server negotiate the use of reconfigure messages. When the client can accept reconfigure messages from the server, then the client includes the Reconfigure Accept option in both solicit and request messages sent to the server.
By default, the DHCPv6 server accepts solicit messages from clients regardless of whether they support reconfiguration. You can specify that the server require clients to accept reconfigure messages. In this case, the DHCPv6 server includes the Reconfigure Accept option in both advertise and reply messages when reconfiguration is configured for the client interface. Solicit messages from nonsupporting clients are discarded and the clients are not allowed to bind.
To configure the DHCPv6 local server to bind only clients that support client-initiated reconfiguration:
Specify strict reconfiguration.
For all DHCPv6 clients:
[edit system services dhcp-local-server dhcpv6 reconfigure]user@host# set strictFor only a particular group of DHCPv6 clients:
[edit system services dhcp-local-server dhcpv6 group group-name reconfigure]user@host# set strict
The show dhcpv6 server statistics command displays a count of solicit messages that the server has discarded.

Configuring DHCPv6 Rapid Commit (MX Series, EX Series)
You can configure the DHCPv6 local server to support the DHCPv6 Rapid Commit option (DHCPv6 option 14). When rapid commit is enabled, the server recognizes the Rapid Commit option in Solicit messages sent from the DHCPv6 client. (DHCPv6 clients are configured separately to include the DHCPv6 Rapid Commit option in the Solicit messages.) The server and client then use a two-message exchange (Solicit and Reply) to configure clients, rather than the default four-message exchange (Solicit, Advertise, Request, and Reply). The two-message exchange provides faster client configuration, and is beneficial in environments in which networks are under a heavy load.
You can configure the DHCPv6 local server to support the Rapid Commit option globally, for a specific group, or for a specific interface. By default, rapid commit support is disabled on the DHCPv6 local server.
To configure the DHCPv6 local server to support the DHCPv6 Rapid Commit option:
- Specify that you want to configure the overrides options: [edit system services dhcp-local-server dhcpv6]user@host# edit overrides
- Enable rapid commit support:[edit system services dhcp-local-server dhcpv6 overrides]user@host# set rapid-commit
Allow Host Inbound Traffic for DHCPv6 Traffic
For the DHCPv6 server to allow DHCPv6 requests, you must configure host inbound traffic system services to allow DCHPv6 traffic. In this example, the zone my-zone allows DHCPv6 traffic from the zone untrust, and the ge-0/0/3.0 interface is configured with the IPv6 address 2001:db8:3001::1.
To create a security zone policy to allow DHCPv6 on SRX1500, SRX5400, SRX5600, and SRX5800 devices:
- Create the zone and add an interface to that zone.[edit security zones]user@host# edit security-zone my-zone interfaces ge-0/0/3.0
- Configure host inbound traffic system services to allow
DCHPv6.[edit security zones security-zone my-zone interfaces ge-0/0/3.0]user@host# set host-inbound-traffic system-services dhcpv6
- If you are done configuring the device, enter commit from configuration mode.

Understanding Cascaded DHCPv6 Prefix Delegating
You can use DHCPv6 client prefix delegation to automate the delegation of IPv6 prefixes to the customer premises equipment (CPE). With prefix delegation, a delegating device delegates IPv6 prefixes to a requesting device. The requesting device then uses the prefixes to assign global IPv6 addresses to the devices on the subscriber LAN. The requesting device can also assign subnet addresses to subnets on the LAN.
With cascaded prefix delegation, the IPv6 address block is delegated to a DHCPv6 client that is running on the WAN interface of a customer edge device. The identity association (IA) for the client is used for the identity association for prefix delegation (IA_PD). The CE device requests, through DHCPv6, an IPv6 address with the IA type of nontemporary addresses (IA_NA). Both IA_PD and IA_NA are requesting in the same DHCPv6 exchange.
The topology in Figure 1shows an SRX Series device acting as the CPE. The WAN interface links to the provider edge (PE) device and the LAN interfaces link to the customer networks. The service provider delegates a prefix (delegated-prefix) and an IPv6 address (cpe-wan-ipv6-address) to a DHCPv6 client. When a requesting device receives that IPv6 address through the DHCPv6 client, the device must install the IPv6 address on its WAN interface. The DHCPv6 client then divides the delegated prefix into sub-prefixes and subsequently assigns them to the connected LAN interfaces of the CPE device, making some subset of the remaining space available for sub-prefix delegation.
A CPE assigns sub-prefixes to its LAN interfaces and broadcasts the sub-prefixes through device advertisement. In this scenario, the CPE acts as a sub-PE and delegates sub-prefixes and assigns them to sub-CPEs.
The requirements of sub-prefix delegation are the same as for the prefix delegation defined in RFC 3769.
There can be multi-level sub prefix delegations, see Figure 2. The top level CPE gets a delegated prefix from the PE and delegates the sub prefixes to second level sub-CPEs, then to the third level sub-CPEs, and finally to the end levels. The end level sub-CPEs assign the IPv6 address to end hosts through SLAAC, stateless DHCPv6 or stateful DHCPv6. This is called cascaded prefix delegating.
Example - Configuring DHCPv6 Prefix Delegation (PD) over Point-to-Point Protocol over Ethernet (PPPoE)
This example shows how to configure DHCPv6 PD over PPPoE on SRX Series devices.
Requirements
No special configuration beyond the device initialization is required before configuring this feature.
Overview
The example uses SRX550M devices for configuring DHCPv6 PD over PPPoE. Before you begin, configure DHCPv6 server to permit in host-inbound traffic and receive DHCPv6 packet. Provide a host-name to establish PPPoE session. To enable IPv6, chassis reboot is required.
Configuring DHCPv6 PD over PPPoE involves the following configurations:
Configuring DHCPv6 Server
DHCPv6 Client (PD)
DHCPv6 Client (Auto)
Topology
The following illustration describes DHCPv6 PD over PPPoE topology which provide a configuration suite using SRX Series devices.
