Configuring the state of Address Allocation

You can configure the address assignment status based on the address assignment mode and access mode.

Context

If the address assignment mode is IA_NA or IA_NA+IA_PD, stateful address assignment (M = 1) needs to be configured.

The M flag being 1 indicates that clients obtain addresses and other configuration information in stateful mode.

Procedure

Configure the address assignment status on an interface.
- For IPoE users, configure the address assignment status in the interface view:
  1. Run system-view
    The system view is displayed.
  2. Run interface interface-type interface-number
    The interface view is displayed.
  3. Run ipv6 nd autoconfig managed-address-flag
    The interface is configured to use stateful autoconfiguration to obtain IPv6 addresses.
  4. Run ipv6 nd autoconfig other-flag
    The interface is configured to use stateful autoconfiguration to obtain other configuration information.
  5. Run commit
    The configuration is committed.
  6. (Optional) Configure a unicast destination address for RA messages.
    - Run the bas command to enter the BAS interface view.
    - Run the commit command to commit the configuration.
    - Run the ipv6 nd ra unicast command to configure the router to send RA messages that carry a unicast destination addresses in response to IPoE user access requests.
    - Run the commit command to commit the configuration.
- For PPPoE users, configure the address assignment status in the domain view.
  1. Run system-view
    The system view is displayed.
  2. Run aaa
    The AAA view is displayed.
  3. Run domain domain-name
    A domain is created and the domain view is displayed.
  4. Run commit
    The configuration is committed.
  5. Run ipv6 nd autoconfig managed-address-flag [ interface-id ipv6cp ]
    Stateful address assignment is configured for PPPoE users.
  6. Run ipv6 nd autoconfig other-flag { ndra | dhcpv6 | dhcpv6-enhance }
    The router is configured to assign other configuration information using NDRA or stateless DHCPv6 when IPv6 addresses are assigned in NDRA mode.
  7. (Optional) Run prefix-assign-mode unshared
    The IPv6 prefix assignment mode is set to unshared. That is, IPv6 users do not share the same IP prefix.
  8. (Optional) Run dhcpv6-follow-ipv6cp wait-delay { time-value | infinity }
    The timeout period for waiting for a DHCPv6 connection request from a PPPoE user is configured.
  9. (Optional) Run ipv6 nd ra unicast
    The router is configured to send RA messages that carry a unicast destination address in response to PPPoE user access requests.
  10. Run commit
    The configuration is committed.
