# aaa dhcpv6-delegated-prefix delegated-ipv6-prefix

#### Syntax

[ no ] aaa dhcpv6-delegated-prefix delegated-ipv6-prefix

#### Release Information

Command introduced in JunosE Release 10.1.0.

#### Description

Sets the Delegated-IPv6-Prefix RADIUS attribute to be used for DHCPv6 Prefix Delegation. The no version restores the default behavior, which causes the Framed-IPv6-Prefix RADIUS attribute to be used for Prefix Delegation.

| Note: If you configured the Framed-IPv6-Prefix attribute to be used for IPv6 Neighbor Discovery router advertisements by using the aaa ipv6-nd-ra-prefix framed-ipv6-prefix command, you must also issue the aaa dhcpv6-delegated-prefix delegated-ipv6-prefix command after you issue the aaa ipv6-nd-ra-prefix framed-ipv6-prefix command to enable the use of the Delegated-IPv6-Prefix attribute for DHCPv6 Prefix Delegation. Otherwise, the Framed-IPv6-Prefix attribute will be used for both IPv6 Neighbor Discovery router advertisements and DHCPv6 Prefix Delegation.

#### Mode

Global Configuration
