Address for Multi-segment Network — Before you can assign an IPv6 address to the
switch that will be used to connect to a multi-segment network, you must obtain
the following information from your network administrator:
◆ Prefix for this network
◆ IP address for the switch
◆ Default gateway for the network
For networks that encompass several different subnets, you must define the full
address, including a network prefix and the host address for the switch. You can
specify either the full IPv6 address, or the IPv6 address and prefix length. The prefix
length for an IPv6 network is the number of bits (from the left) of the prefix that
form the network address, and is expressed as a decimal number. For example, all
IPv6 addresses that start with the first byte of 73 (hexadecimal) could be expressed
as 73:0:0:0:0:0:0:0/8 or 73::/8.
To generate an IPv6 global unicast address for the switch, complete the following
steps:
1. From the global configuration mode prompt, type “interface vlan 1” to access
the interface-configuration mode. Press <Enter>.
2. From the interface prompt, type “ipv6 address ipv6-address” or “ipv6 address
ipv6-address/prefix-length,” where “prefix-length” indicates the address bits
used to form the network portion of the address. (The network address starts
from the left of the prefix and should encompass some of the ipv6-address
bits.) The remaining bits are assigned to the host interface. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the IPv6 default gateway for the network to which the
switch belongs, type “ipv6 default-gateway gateway,” where “gateway” is the
IPv6 address of the default gateway. Press <Enter>.
