PPPoE server IPv6 address assignment through ND and IPv6CP negotiation configuration example

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.

Configuration procedure

# Create Virtual-Template 10.

<Router> system-view
[Router] interface virtual-template 10

# Configure Virtual-Template 10 to use PAP to authenticate the peer.

[Router-Virtual-Template10] ppp authentication-mode pap domain system

# Configure an IPv6 address for Virtual-Template 10.

[Router-Virtual-Template10] ipv6 address 2001::1 64

# Enable Virtual-Template 10 to advertise RA messages.

[Router-Virtual-Template10] undo ipv6 nd ra halt
[Router-Virtual-Template10] quit

# Enable the PPPoE sever on GigabitEthernet 2/1/1, and bind the interface to Virtual-Template 10.

[Router] interface gigabitethernet 2/1/1
[Router-GigabitEthernet2/1/1] pppoe-server bind virtual-template 10
[Router-GigabitEthernet2/1/1] quit

# Configure a PPPoE user.

[Router] local-user user1 class network
[Router-luser-network-user1] password simple pass1
[Router-luser-network-user1] service-type ppp
[Router-luser-network-user1] quit

# Configure an IPv6 prefix authorized to the user in the ISP domain.

[Router] domain system
[Router-isp-system] authorization-attribute ipv6-prefix 2003:: 64
[Router-isp-system] quit

# Display PPP user information on GigabitEthernet 2/1/1.
