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

COMMAND

DESCRIPTION

enable

Turns on the IPv6 interface.

nd ra accept

Sets the IPv6 interface to accept IPv6 neighbor discovery router

 

advertisement messages.

 

 

nd ra advertise

Sets the IPv6 interface to send IPv6 neighbor discovery router

 

advertisement messages.

nd ra managed-config-flag

Turns on 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 on 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 <1280..1500> <0>

Sets the Maximum Transmission Unit (MTU) size of IPv6 packets sent on

 

the interface.

nd ra hop-limit <0..255>

Sets the maximum number of hops for router advertisements and all

 

IPv6 packets originating from the interface.

 

 

nd ra router-preference { low

Sets the Default Router Preference (DRP) extension metric (low,

medium high }

medium, or high) in the interface’s IPv6 neighbor discovery router

 

advertisement messages.

nd ra prefix-advertisement

Sets the IPv6 prefix that the ZyWALL advertises to its clients, whether

ipv6_addr_prefix [ auto { on off }

or not to advertise it, and how long before the prefix’s preference and

] [ link{ on off } ] [ preferred-

lifetime expire.

time { <0..4294967294> infinity }]

 

[valid-time{ <0..4294967294>

 

infinity }]

 

nd ra min-rtr-interval <3..1350>

Sets the minimum IPv6 router advertisement transmission interval.

nd ra max-rtr-interval <4..1800>

Sets the maximum IPv6 router advertisement transmission interval.

nd ra reachable-time <0..3600000>

Sets the amount of time a remote IPv6 node is considered reachable

 

after a reachability confirmation event.

nd ra default-lifetime <4..9000>

Sets the router lifetime value is included in all IPv6 router

 

advertisements sent out the interface. The router lifetime value should

 

be equal to or greater than the router advertisement interval.

 

 

nd ra retrans-timer <0..4294967295>

Sets the IPv6 router advertisement retransmission interval in

 

milliseconds.

ipv6 address dhcp6_profile

Has the ZyWALL obtain an IPv6 prefix from the ISP or a connected

dhcp6_suffix_128

uplink router for an internal network, such as the LAN or DMZ.

 

dhcp6_profile: Specify the DHCPv6 request object to use.

 

dhcp6_suffix_128: Specify the ending part of the IPv6 address, a slash

 

(/), and the prefix length. The ZyWALL appends it to the delegated

 

prefix.

 

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

 

want to configure an IP address of 2003:1234:5678:1111::1/128 for

 

this interface, then enter ::1111:0:0:0:1/128 for the

 

dhcp6_suffix_128.
