Configuring an IPv6 delegation address pool includes binding a prefix pool to the address pool and configuring a preference and other services (such as a DNS or DNS suffix) for the address pool.
A prefix pool can be bound to only one address pool. Similarly, an address pool can be bound only to one prefix pool. Table 1 shows the binding between address pools and prefix pools.
Among address pools of the same type, a greater priority value indicates a higher priority.
In NDRA address allocation mode, BAS local address pools are used to allocate shared prefixes, whereas BAS delegation address pools are used to allocate unshared prefixes. A BAS delegation address pool configured with slaac-unshare-only takes precedence over other BAS delegation address pools.
An IPv6 address pool whose addresses are in use cannot be deleted. To delete an IPv6 address pool, first run the lock command in the IPv6 address pool view to lock the pool and then delete it after all online users have logged out.
Only one domain name suffix can be set for an IPv6 address pool.
A maximum of two DNS servers can be bound to an IPv6 address pool.
If an IPv6 address pool has been bound to a domain, the address lease cannot be changed.
The system view is displayed.
An IPv6 delegation address pool is created, and the corresponding address pool view is displayed.
The IPv6 address pool is bound to an IPv6 prefix pool.
A priority value is set for the IPv6 address pool.
The default value is 255.
A DNS suffix is configured for domain name resolution.
A DNS server is specified for an IPv6 address pool. An IPv6 address is used to specify a DNS server.
A lease renewal time and a rebinding time are set for the IPv6 address pool.
Or run option code { suboption sub-code { ipv6-address ipv6-address | string string-value } } & <1-16>
A custom DHCPv6 option is configured.
Return to the system view.
The device is configured to assign addresses from IPv6 delegation address pools in round-robin mode.
The configuration is committed.
