Example for Configuring an IPv6 PPPoE Client (Stateless Address Autoconfiguration)

Networking Requirements

The FW shown in Figure 1 functions as an IPv6 PPPoE client and uses stateless address autoconfiguration to obtain an IPv6 address from an IPv6 PPPoE server.

Figure 1 Networking diagram for configuring an IPv6 PPPoE client

Configuration Roadmap

The configuration roadmap is as follows:

Create a PPPoE session and bind it to GigabitEthernet 0/0/1 of the FW to enable the interface to access an IPv6 network.
Create a PPPoE user on a PPPoE server.
Enable stateless address autoconfiguration on FW so that a dialer interface can automatically obtain an IPv6 address.
Configure a global unicast address for GigabitEthernet 0/0/1 on the PPPoE server and enable RA advertisement to advertise the IPv6 prefix to GigabitEthernet 0/0/1 of the FW using a router advertisement (RA) message.

Procedure

Configure the FW.

# Configure the FW as an IPv6 PPPoE client.

<FW> system-view
[FW] interface Dialer1
[FW-Dialer1] link-protocol ppp
[FW-Dialer1] ppp pap local-user admin-example password cipher Admin@123
[FW-Dialer1] dialer user admin-example
[FW-Dialer1] dialer bundle 1
[FW-Dialer1] quit

# Enable IPv6.

[FW] ipv6

# Assign a link-local IPv6 address to a dialer interface.

[FW]interface Dialer1
[FW-Dialer1] ipv6 enable
[FW-Dialer1] ipv6 address auto link-local

# Enable stateless address autoconfiguration.

[FW-Dialer1] ipv6 address auto global
[FW-Dialer1] quit

# Configure a PPPoE session.

[FW] interface GigabitEthernet 0/0/1
[FW-GigabitEthernet0/0/1] pppoe-client dial-bundle-number 1 ipv6
[FW-GigabitEthernet0/0/1] quit

# Assign the dialer interface to a security zone.

[FW] firewall zone trust
[FW-zone-trust] add interface GigabitEthernet 0/0/1
[FW-zone-trust] add interface Dialer 1
[FW-zone-trust] quit

Configure a PPPoE server. The actual configuration varies depending on devices.
# Create a PPPoE user and set the user name to admin-example and the password to Admin@123, which are the same as those specified on the PPPoE client.

# Set the global unicast address to 3001::1/64 for the interface that directly connects the PPPoE server to the PPPoE client.

# Enable RA message advertisement.

Verifying the Configuration

After the configuration is complete, verify the configuration.

Check PPPoE sessions on the firewall.

Check the access users on the router.
