Configuring a Remote IPv6 Address Pool

Procedure

1. Run system-view

   The system view is displayed.

2. Run ipv6 pool pool-name bas remote

   A remote IPv6 address pool is created, and the corresponding address pool view is displayed.

3. Run prefix prefix-name

   An IPv6 prefix pool is bound to the remote IPv6 address pool.

4. (Optional) Run preference preference-value

   A preference is configured for the remote IPv6 address pool.

5. Run export host-route

   The device is enabled to advertise host routes in the remote IPv6 address pool.

6. (Optional) Configure an address assignment mode for remote IPv6 address pools.
   

   By default, the device assigns addresses from address pools in sequence. You can also configure the device to assign addresses from address pools based on the weights of the address pools or in round-robin mode.

   • If the device is configured to assign addresses from address pools in sequence, it selects remote IPv6 address pools for address assignment based on their configuration sequence. For example, three remote IPv6 address pools are configured in a domain. When all users go online, the device selects the first address pool for address assignment. If the first address pool is exhausted, the device selects the second address pool. This process repeats until all users are assigned addresses.
   • If the device is configured to assign addresses from address pools based on their weights, it assigns addresses based on the weight configured for each address pool.
   • If the device is configured to assign addresses from remote IPv6 address pools in round-robin mode, it selects the address pools in turn. For example, three remote IPv6 address pools are configured in a domain. When the first user goes online, the device selects the first address pool; when the second user goes online, the device selects the second address pool; when the third user goes online, the device selects the third address pool; when the fourth user goes online, the device selects the first address pool; when the fifth user goes online, the device selects the second address pool. This process repeats until all users are assigned addresses.
   • Configure the device to assign addresses from remote IPv6 address pools based on the weights of the address pools.
     1. Run weight weight-value

        A weight is configured for the remote IPv6 address pool.

     2. Run commit

        The configuration is committed.

     3. Run quit

        Return to the system view.

     4. Run ipv6-pool algorithm loading-share remote

        The device is configured to assign addresses from remote IPv6 address pools based on the weights of the address pools.

   • Configure the device to assign addresses from remote IPv6 address pools in round-robin mode.

     Run ipv6-pool algorithm round-robin remote

     The device is configured to assign addresses from remote IPv6 address pools in round-robin mode.

7. (Optional) Set an alarm threshold for the address usage of the IPv6 address pool bound to a VPN instance.
   1. Run quit

      Return to the system view.

   2. Run ip vpn-instance vpn-instance-name

      The VPN instance view is displayed.

   3. Run ipv6-family

      The VPN instance IPv6 address family view is displayed.

   4. Run ipv6-pool warning-threshold threshold

      An alarm threshold is set for the address usage of the IPv6 address pool bound to the VPN instance, so that the NetEngine 8000 F generates an alarm when the address usage reaches the threshold.

8. Run commit

   The configuration is committed.
