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.
Note In the ipv6 address interface configuration command, you must enter the ipv6-address and ipv6-prefix
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.

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.)

Not all features discussed in this chapter are supported by the switch. See the

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