What is IPv6 DHCP PD?

What is IPv6 DHCP PD?

Quick Definition: Prefix delegation, also known as PD, is one of the methods available in IPv6 for communicating information to a device about what networks are available for subnetting. Service providers can assign customers a prefix to be used on their own internal networks.

What is enable DHCP PD?

The prefix delegation feature lets a DHCP server assign prefixes chosen from a global pool to DHCP clients. The DHCP client can then configure an IPv6 address on its LAN interface using the prefix it received.

Does DHCP work with IPv6?

Virtually all DHCP server vendors support both protocols so you can use the same management interface for IPv4 and IPv6. There are several benefits that make it advantageous for an enterprise to use DHCPv6.

How does IPv6 prefix delegation work?

With prefix delegation, a delegating router (the BNG) delegates IPv6 prefixes to a requesting router (the CPE). The requesting router then uses the prefixes to assign global IP addresses to the devices on the subscriber LAN. The requesting router can also assign subnet addresses to subnets on the LAN.

What is stateless and stateful IPv6?

The stateless approach is used when a site is not concerned with the exact addresses that hosts use. However, the addresses must be unique. The addresses must also be properly routable. The stateful approach is used when a site requires more precise control over exact address assignments.

What is IPv6 subnet?

IN IPv6, the subnet ID defines an administrative subnet of the network and is up to 16 bits in length. You assign a subnet ID as part of IPv6 network configuration. The subnet prefix defines the site topology to a router by specifying the specific link to which the subnet has been assigned.

Is DHCPv6 encrypted?

Several new messages and options have been proposed to allow the DHCPv6 message to be encrypted and to allow the use of RA message to convey the server’s public key to DHCPv6 clients.

What is IPv6 subnet prefix length?

The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128.

Should I use stateless or stateful IPv6?

Should IPv6 be stateful or stateless?

IPv6 defines mechanisms for both stateful address and stateless address autoconfiguration. Stateless autoconfiguration requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism enables a host to generate its own addresses.
