Juniper EX3400 Features Guide

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.
NOTE: 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:
1. Specify that you want to configure override options.
[edit system services dhcp-local-server dhcpv6]
user@host# edit overrides
2. 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.
