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:
•
•
•
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:

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.

Default IPv6 Configuration (continued)
Default Setting
1
Disabled (IPv4 CEF and dCEF are enabled by default).
Note
None configured.
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
and Unicast Routing Features" section on page
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).
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
When IPv6 routing is enabled, CEFv6 and dCEFv6 are automatically
enabled.
