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:

  1. Set address-assignment pool name, family name, and prefix.
  2. Set range.
