Chapter 51. IPv6 Configuration
IPv6 Protocol’s Configuration
51.1
The configuration of the IPv6 address of the router only takes effect on the VLAN interface, not on the
physical interface.
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
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.
