Configuring IPv6
Default IPv6 Configuration
Table 39-1 shows the default IPv6 configuration.
Configuring IPv6 Addressing and Enabling IPv6 Host Functions or Routing
This section describes how to assign IPv6 addresses to individual Layer 3 interfaces and to globally
forward IPv6 traffic on the switch.
Before configuring IPv6 on the switch, consider these guidelines:
• Be sure to select a dual IPv4 and IPv6 SDM template.
• Not all features discussed in this chapter are supported by the switch. See the “Unsupported IPv6
and Unicast Routing Features” section on page 39-8 .
• In the ipv6 address interface configuration command, you must enter the ipv6-address and
ipv6-prefix variables with the address specified in hexadecimal using 16-bit values between colons.
The prefix-length variable (preceded by a slash [/]) is a decimal value that shows how many of the
high-order contiguous bits of the address comprise the prefix (the network portion of the address).
To forward IPv6 traffic on an interface, you must configure a global IPv6 address on that interface.
Configuring an IPv6 address on an interface automatically configures a link-local address and activates
IPv6 for the interface. The configured interface automatically joins these required multicast groups for
that link:
• solicited-node multicast group FF02:0:0:0:0:1:ff00::/104 for each unicast address assigned to the
interface (this address is used in the neighbor discovery process.)
• all-nodes link-local multicast group FF02::1
• all-routers link-local multicast group FF02::2
For more information about configuring IPv6 host functions or routing, see the “Implementing
Addressing and Basic Connectivity for IPv6” chapter in the Cisco IOS IPv6 Configuration Library on
Cisco.com.
