Configuring IPv6 Addressing and Enabling IPv6 Routing

This section describes how to assign IPv6 addresses to individual Layer 3 interfaces and enable the
forwarding of IPv6 traffic globally on the switch.
In the ipv6 address interface configuration command, you must enter the ipv6-address and ipv6-prefix
Note
variables in the form documented in RFC 2373 where the address is 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).
For an interface to forward IPv6 traffic, you must configure an IPv6 address on the interface.
Configuring a global 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:

Before configuring IPv6 on the switch, be sure to select a dual IPv4 and IPv6 SDM template.

IPv6" chapter in the Cisco IOS IPv6 Configuration Library at this URL:

Default IPv6 Configuration
Default Setting
Default desktop or default aggregator (Catalyst 3750-12S)
Disabled globally and on all interfaces
Disabled (IPv4 CEF and dCEF are enabled by default)
Note
None configured
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
Not all features discussed in this chapter are supported by the Catalyst 3750 switch. See the
"Unsupported IPv6 Unicast Routing Features" section on page
When IPv6 routing is enabled, CEFv6 and dCEF6 are automatically
enabled.
