DHCPv6 Configuration Examples

This section contains the following examples:

• Configuring a DHCPv6 Stateless Server

• Configuring the DHCPv6 Server for Prefix Delegation

• Configuring an Interface as a DHCPv6 Relay Agent

Configuring a DHCPv6 Stateless Server

This example configures a DHCPv6 pool that will provide information for the

DHCPv6 server to distribute to DHCPv6 clients that are members of VLAN

100. To define stateless information for the DHCPv6 server to distribute,

multiple DNS domain names and DNS server addresses are defined within

the pool.

VLAN routing interface 100 is configured as a DHCPv6 server. Setting NDP

on the interface to send the other-config-flag option allows the interface to

prompt DHCPv6 clients to request only stateless server information.

To configure the switch:

Enable the DHCPv6 feature.

console#configure

console(config)#service dhcpv6

Create the DHCPv6 pool and configure stateless information.

console(config)#ipv6 dhcp pool my-pool

console(config-dhcp6s-pool)#domain-name pengo.dell.com

console(config-dhcp6s-pool)#domain-name dell.com

console(config-dhcp6s-pool)#dns-server 2001:DB8:A328:22C::1

console(config-dhcp6s-pool)#dns-server 2001:DB8:A328:22C::2

Configure VLAN 100 as a routing interface and assign a globally unique

IPv6 address.

console(config)#interface vlan 100

console(config-if-vlan100)#ipv6 address

2001:DB8:A328:34B::11/32

Configure the DHCPv6 server functionality on VLAN 100. Clients can use

the preference value to determine which DHCPv6 server to use when

multiple servers exist.

console(config-if-vlan100)#ipv6 dhcp server my-pool preference
