195
valid-lifetime valid-lifetime: Specifies the valid lifetime of the prefixes to be assigned. The value ranges
from 60 to 4,294,967,295, in seconds. The default value is 2,592,000 seconds, that is, 30 days. The
valid lifetime must be greater than or equal to the preferred lifetime.
Description
Use the prefix-pool command to apply a prefix pool to the DHCPv6 address pool, so that the DHCPv6
server can dynamically select a prefix from the prefix pool and assign it to the client.
Use the undo prefix-pool command to remove the configuration.
No prefix pool is referenced by an address pool by default.
A non-existing prefix pool can be referenced by an address pool. However, no prefix is available in the
prefix pool for dynamic prefix assignment until the prefix pool is created.
You cannot modify the prefix pool referenced by an address pool, or the preferred lifetime or valid
lifetime by using the prefix-pool command. You need to remove the configuration before you can have
another prefix pool referenced by the address pool, or modify the preferred lifetime and valid lifetime.
NOTE:
Only one prefix pool can be referenced by an address pool.
Examples
# Apply prefix pool 1 to address pool 1, and use the default preferred lifetime and valid lifetime.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] prefix-pool 1
# Apply prefix pool 1 to address pool 1, and set the valid lifetime to three days, the preferred lifetime to
one day.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] prefix-pool 1 preferred-lifetime 86400 valid-lifetime 259200
