Configuration restrictions and guidelines
Only one prefix pool can be referenced by an address pool.
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 must remove the configuration before you can have another prefix pool referenced by the address pool, or modify the preferred lifetime and valid lifetime.
You can configure up to eight DNS server addresses, one domain name, eight SIP server addresses, and eight SIP server domain names in an address pool.
