Users Manual of GPL-8000
The IPv6 protocol is disabled in default state. If the IPv6 protocol need be used on a VLAN interface, this
protocol should be first enabled in VLAN interface configuration mode. To enable the IPv6 protocol, users
have to set the IPv6 address. If on a VLAN interface at least one IPv6 address is set, the VLAN interface can
handle the IPv6 packets and communicates with other IPv6 devices.
To enable the IPv6 protocol, users should finish the following task:
Setting at least one IPv6 address in VLAN interface configuration mode
Enabling IPv6
51.2.1 Setting the IPv6 Address
The IPv6 address is used to determine the destination address to which the IPv6 packets can be sent. There
are three kinds of IPv6 addresses.
Kind Referred Format Remarks
Unicast
address
2001: 0: 0: 0: 0DB8: 800:
200C: 417A/64
2001: 0: 0: 0: 0DB8: 800: 200C: 417A
stands for a unicast address, while 64 stands for the
length of the prefix of this address.
Multicast
address
FF01: 0: 0: 0: 0: 0: 0:
101
All multicast addresses begin with FF.
Any address 2002: 0: 0: 0: 0DB8: 800:
200C: 417A/64
The format of this address is the same as that of the
unicast address. Different VLAN interfaces can be set
to have the same address, no matter it is a
unicast/broadcast/multicast address.
For the further details of the IPv6 address, see RFC 4291.
In order to enable IPv6, users must set a unicast address in VLAN interface configuration mode. The set
unicast address must be one or multiple addresses of the following type:
IPv6 link-local address
Global IPv6 address
To set an IPv6 link-local address in VLAN interface configuration mode, run the following commands.
Command Purpose
ipv6 enable Sets a link-local address automatically.
ipv6 address fe80: : x link-local Sets a link-local address manually.
The link-local address must begin with fe80.The default length of the prefix is 64
bit.At manual settings only the values at the last 64 bits can be designated.
On a VLAN interface can only one link-local address be set.
After IPv6 is enabled through the configuration of the link-local address, IPv6 only takes effect on the local
