IPv6 prefix length. Default IPv6 gateway. Primary DNS server address.If you configure a stateful DHCPv6 server for the LAN, you need to add local DHCP IPv6 address pools so the DHCPv6 server can control the allocation of IPv6 addresses in the LAN. ipv6 dhcp pool DHCPCUSTOMERS prefix-delegation pool DHCPPOOL. ! interface e1/0.RA message. interface e0/0 ipv6 address 2001:ffXX:0:ff02::a/64 ipv6 dhcp client pd PREFIX no shutdown. ipv6 dhcp pool IPv6DualStack prefix-delegation pool prefix-pool-IPv6DualStack lifetime 3600 3600 address prefix 2001:2:B:C::/60 dns-server FC00:1:1:1::8888 dns-server FC00:1:1:1::8844Leave a Reply Cancel reply. Your email address will not be published. Required fields are marked . In this example, all addresses are assigned dynamically from this local pool prefix. However, you can also assign addresses statically by associating the IPv6 address with the DHCP Unique Identifier (DUID), as follows DHCPv6 Stateful Configuration. Lets configure the stateful pool, it is similar to doing this for IPv4Information refresh time: 0 Prefix Rapid-Commit: disabled Address Rapid-Commit: disabled. The show ipv6 dhcp interface command shows us what DNS and domain information we received, this is ipv6-address/prefix-length — Specifies the IPv6 prefix pool-name — The name of DHCPv6 local server pool.

Table 6 lists the mappings between address types and format prefixes. DHCP clients uses the DHCP server to obtain the other useful configuration information (such as the address of DNS servers).

An example of an IPv6 prefix and prefix length is 3ffe:1::1234/64.no ipv6 dhcp pool. This command removes the specified DHCPv6 pool. The IPv6 local address pool for DHCP is an object that contains information about prefix configuration parameters and guidelines that govern the assignment of these prefixes to requesting routers.

If all goes well you should be able to see your IPv6 delegated prefix The only way to overcome this is to use an IOS supporting IANA (12.4(24) T) as I mentioned in a previous post with different implementation commands of DHCPv6 server using address-prefix under ipv6 DHCP pool. ! !

Advertisementundo ipv6 dhcp pool pool-nameA DHCPv6 address pool stores IPv6 address/prefix and other configuration parameters to be In stateless configuration mode the dhcp server interacts together with an other IPv6 address assignment mechanism (e.g. a radvd router).
