 shows the default IPv6 configuration.

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 Catalyst 3560 switch. See the 

.

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 routing, see the “Implementing Addressing and Basic 
Connectivity for IPv6” chapter in the Cisco IOS IPv6 Configuration Library on Cisco.com.

SDM template

Default 

IPv6 routing

Disabled globally and on all interfaces.

CEFv6 or dCEFv6

Disabled (IPv4 CEF and dCEF are enabled by default).

When IPv6 routing is enabled, CEFv6 and dCEF6 are automatically 
enabled.

IPv6 addresses

None configured.
