Table 16 interface General Commands: Basic Properties and IP Address Assignment (continued)

COMMAND

DESCRIPTION

nd ra prefix-advertisement

Configures the network prefix to use a delegated prefix as the beginning

dhcp6_profile dhcp6_suffix_64

part of the network prefix.

 

dhcp6_profile: Specify the DHCPv6 request object to use for

 

generating the network prefix for the network.

 

dhcp6_suffix_64: Specify the ending part of the IPv6 network address

 

plus a slash (/) and the prefix length. The ZyWALL appends it to the

 

selected delegated prefix. The combined address is the network prefix

 

for the network.

 

For example, you got a delegated prefix of 2003:1234:5678/48. You

 

want to divide it into 2003:1234:5678:1111/64 for this interface and

 

2003:1234:5678:2222/64 for another interface. You can use ::1111/64

 

and ::2222/64 for the suffix address respectively. But if you do not want

 

to divide the delegated prefix into subnetworks, enter ::0/48 here,

 

which keeps the same prefix length (/48) as the delegated prefix.

 

 

dhcp6 { server client relay upper

Sets the IPv6 interface to be a DHCPv6 server, client or relay. For relay,

{ config_interface ipv6_addr } }

specify an interface from which to get the DHCPv6 server’s address or

 

the IPv6 address of a DHCPv6 server.

 

 

dhcp6 rapid-commit

This shortens the DHCPv6 message exchange process from four to two

 

steps to help reduce network traffic.

 

Note: Make sure you also enable this option in the DHCPv6 clients to

 

make rapid commit work.

 

 

dhcp6 address-request

Get this interface’s IPv6 address from the DHCPv6 server.

dhcp6 refresh-time {

Sets the number of seconds a DHCPv6 client should wait before

<600..4294967294> infinity }

refreshing information retrieved from DHCPv6.

dhcp6 duid { duid mac }

Specify the DHCP Unique IDentifier (DUID) of the interface or have it

 

generated from the interface’s default MAC address.

 

 

dhcp6-lease-object dhcp6_profile

For a DHCPv6 server interface, specify the profile of DHCPv6 lease

 

settings to offer to DHCPv6 clients.

 

 

dhcp6-request-object dhcp6_profile

For a DHCPv6 client interface, specify the profile of DHCPv6 request

 

settings that determine what additional information to get from the

 

DHCPv6 server.

 

 

interface interface_name no ipv6

Enters the sub-command mode for deleting the specified IPv6 address

 

or removing it’s settings.

 

 

enable

Turns off the IPv6 interface.

address ipv6_addr_prefix

Removes the IPv6 interface’s IPv6 prefix setting.

gateway

Removes the IPv6 interface’s gateway setting.

nd ra accept

Sets the IPv6 interface to discard IPv6 neighbor discovery router

 

advertisement messages.

nd ra advertise

Has the IPv6 interface not send IPv6 neighbor discovery router

 

advertisement messages.

 

 

nd ra managed-config-flag

Turns off the flag in IPv6 router advertisements that tells hosts to use

 

managed (stateful) protocol for address autoconfiguration in addition to

 

any addresses autoconfigured using stateless address

 

autoconfiguration.

 

 

nd ra other-config-flag

Turns off the other stateful configuration flag in IPv6 router

 

advertisements that tells hosts to use administered (stateful) protocol to

 

obtain autoconfiguration information other than addresses.

 

 

nd ra mtu

Removes the Maximum Transmission Unit (MTU) size setting for IPv6

 

packets the interface sends.

 

 

60
