PPPoE server IPv6 address assignment through ND and IPv6CP
negotiation configuration example
Network requirements
As shown in Figure 15, configure the PPPoE server to advertise the following information to the host:
• IPv6 prefix in RA messages.
• IPv6 interface identifier during IPv6CP negotiation.
The host uses the IPv6 prefix and IPv6 interface identifier to generate an IPv6 global unicast address.
