Best Practice: DHCPv6 Prefix Delegation over a PPPoE Access Network
When you use DHCPv6 prefix delegation over a PPPoE access network, you need to enable unnumbered addressing in the family inet6 configuration.
For dynamic PPPoE interfaces, enable unnumbered addressing in the dynamic profile. For example:
[edit dynamic-profiles]
PPPoE-dyn-ipv4v6-dhcp {interfaces {pp0 {unit "$junos-interface-unit" {. . .family inet6 {unnumbered-address lo0.0;}}}}}
For static PPPoE interfaces, enable unnumbered addressing in the interface configuration. For example:
[edit interface pp0]
unit 2004 {family inet6 {unnumbered-address lo0.0;
