Setting up DHCPv6 client

Configure DHCPv6 client if you want the vRouter to acquire an IPv6 address, parameters, or both from a DHCPv6 server. Refer to the “Ethernet Interfaces” chapter of the Ciena Vyatta Network OS LAN Interfaces Configuration Guide for more information on configuring a DHCPv6 client.

To configure a DHCPv6 client, perform the following steps in configuration mode.

Table 1. Setting up a DHCPv6 client on an Ethernet interface

Step

Command

Enable DHCPv6 client on the dp0p1p1 interface.


vyatta@R1# set interface dataplane dp0p1p1 address dhcpv6 

Commit the change.


vyatta@R1# commit

Show the configuration.


vyatta@R1# show interface dataplane dp0p1p1
   address dhcpv6
   hw-id b6:cc:6a:95:22:b2
Note: After an interface acquires an IPv6 address from a DHCPv6 server, if you shut down the interface by using the set interfaces dataplane interface-name disable command, the interface immediately loses its IPv6 link local address. Without an IPv6 link local address, the DHCPv6 client cannot send a message to the DHCPv6 server to release the IPv6 lease and the lease remains in effect. To avoid this scenario, before shutting down a data plane interface, release the IPv6 lease for the interface by using the release dhcpv6 interface interface-name command.
