Chapter 1 Configuring IPv6 Unicast Routing
Configuring IPv6
To remove an IPv6 address from an interface, use the no ipv6 address ipv6-prefix/prefix length eui-64
or no ipv6 address ipv6-address link-local interface configuration command. To remove all manually
configured IPv6 addresses from an interface, use the no ipv6 address interface configuration command
without arguments. To disable IPv6 processing on an interface that has not been explicitly configured
with an IPv6 address, use the no ipv6 enable interface configuration command. To globally disable IPv6
routing, use the no ipv6 unicast-routing global configuration command.
Step 8
ipv6 address ipv6-prefix/prefix length eui-64
or
ipv6 address ipv6-address/prefix length
or
ipv6 address ipv6-address link-local
or
ipv6 enable
Specify a global IPv6 address with an extended unique identifier
(EUI) in the low-order 64 bits of the IPv6 address. Specify only
the network prefix; the last 64 bits are automatically computed
from the switch MAC address. This enables IPv6 processing on
the interface.
Manually configure an IPv6 address on the interface.
Specify a link-local address on the interface to be used instead
of the link-local address that is automatically configured when
IPv6 is enabled on the interface. This command enables IPv6
processing on the interface.
Automatically configure an IPv6 link-local address on the
interface, and enable the interface for IPv6 processing. The
link-local address can only be used to communicate with nodes
on the same link.
Step 9
exit Return to global configuration mode.
Step 10
ip routing Enable IP routing on the switch.
Step 11
ipv6 unicast-routing Enable forwarding of IPv6 unicast data packets.
Step 12
end Return to privileged EXEC mode.
Step 13
show ipv6 interface interface-id Verify your entries.
Step 14
copy running-config startup-config (Optional) Save your entries in the configuration file.
